Weekend Cat Blogging and Photo Hunt: Digital

The theme of this week’s Photo Hunt is digital. Rather than simply use a digital photo – which could be any photo ever taken of Luna – I chose a couple of images that demonstrate the unique opportunities of the medium. A digital photo is really just a stream of numbers, not unlike digital audio, and can be processed in countless ways using digital signal processing or applying other mathematical functions.

For a piece I originally did in 2007, I took one of Luna’s adoption photos from Santa Cruz County Animal Services and applied an algorithm that overlaid these colored bands, as shown above.  The color bands were generated using a set of hastily chosen trigonometric and hyperbolic functions applied to the timeline of the animation sequence.  These photos are stills from the full animation.

I did these using image and video extensions to Open Sound World – one nice feature of that work was that I could use the same functions for both audio and video, and “see” what a particular audio-processing algorithm looked like when applied to an image.   And I would probably use the Processing environment for future visual work, perhaps in conjunction with OSW.


Weekend Cat Blogging #309 and Carnival of the Cats are both being hosted by Billy SweetFeets this weekend. Perhaps Luna’s animation could be part of one of the dance videos they often feature.

Photo Hunt #264 is hosted by tnchick. This week’s theme is digital.

A special note this week. Our friend Judi at Judi’s Mind over Matter (home of Jules and Vincent) has information on how to help animals affected the storms and tornadoes in the southeast US. They live in Alabama, not far from the place that was hit hardest by the tornadoes. We’re glad they’re safe, and able to provide this information for those who would like to help.

Weekend Cat Blogging and Photo Hunt: Square…and Rememberance

This weekend, we have another combined Weekend Cat Blogging and Photo Hunt. The theme this week is square. Geometric shapes, including squares, abound at CatSynth HQ. But with the exceptionally gorgeous weather, we turn our attention once again to the patio:

The patio is covered in square slate tiles on which Luna enjoys rolling around. We are still doing some work to fix things up for spring now the construction is in the past. New design ideas to emphasize the industrial and geometric aesthetic.


This weekend we are also joining our friends the Three Tabby Cats in Vienna ~ Kashim, Othello and Salome ~ in a Weekend of Remembrance. We participated when they hosted a similar weekend back in 2007, lighting a candle like this one.

As we have made more friends online, so we have also lost many friends. We said goodbye to Mickey only a few weeks ago. Last year, we lost DJ Kikovas, the feline companion of our friend and fellow electronic musician Vivi Pedraglio. We also said goodbye to Tali and Sniffie. It is interesting to look back and see the diverse collection of people, mixture of musicians, engineers and cat lovers, who cross paths in these stories. We have also lost many heroes in music, art and mathematics in this same period of time; and some personal friends. We remember them as well.

Our thoughts for all our friends who lost love ones (human and non-human) over the past year, and for those who are struggling in the current storms in southeastern U.S., recovering from the disaster in Japan, and living through the seemingly greater number conflicts around the world.


Weekend Cat Blogging #308 is hosted by Samantha and Clementine at Life From a Cat’s Perspective. They are dedicating their post in remembrance of Praline.

Photo Hunt #263 is hosted by tnchick. This week’s theme is SQUARE.

The Carnival of the Cats will be up tomorrow at Meowsings of an Opinionated Pussycat.

Weekend Cat Blogging #307: Wild Cats on Earth Day

Every year, we at CatSynth set aside Weekend Cat Blogging on Earth Day to look at some of the wild cat species around the world. In particular, we focus on some of the smaller wild cats, which after often less well known than the big cats such as tigers, lions and leopards, but in many cases just as endangered.

We begin with the Iriomote cat, a critically endangered wildcat found only on the remote Japanese island of Iriomote.

There are estimated to be only 100 or so left in the wild. The main threats, habit removal and non-native species (notably feral domestic cats), are exacerbated by the fact they are exclusive to one island. One third of the island has been declared a wildlife reserve with a Iriomote Wildlife Center set up to study and protect them. But with such a small population, their future remains uncertain.

With all the events and focus on the Middle East and North Africa this year, it also seems appropriate to feature the sand cat (felis margarita).

As their name implies, sand cats are found in deserts, in particular in pockets in Egypt, Tunisia and Morocco in North Africa, on the Arabian Peninsula. But there are also subspecies found in Iran and as far east as Afghanistan and Pakistan. Although not endangered overall, individual local populations are, such as Israel where it became locally extinct. A program by the Jerusalem Zoo aims to re-introduce them.

In looking up information for this article, I came across the International Society for Endangered Cats (ISEC), an organization based in Canada dedicated to “aid in the wild conservation and captive preservation of endangered and threatened small wild cat species though education, scientific observation and support for captive breeding of critically endangered species.” They have several active projects at the moment, including a study of the black-footed cat.

The black-footed cat is found in the southwest of Africa, i.e., Namibia, Botswana and parts of South Africa. They are among the smallest of wild cats, and as nocturnal creatures they are rarely seen. One thing that makes them unusual is that they don’t climb trees but instead burrow into the ground for shelter.

The ISEC is also conducting a study of the Argentine Espinal:

The Argentine Espinal is an arid grassland and shrubland mosaic that has been greatly modified since the 1600’s, when cattle became the prominent species on the landscape. Found today only in fragmented patches, the Espinal was once home to a great diversity of birds, plants and mammals, among them a unique guild of felids composed of the Pampas cat Leopardus colocolo, Geoffroy’s cat Leopardus geoffroyi, Jaguarundi Puma yagouaroundi and Puma Puma concolor.

We have discussed the Geoffroy’s cat in a previous post. They are still relatively common and have a large range in southern South America. However, they are classified as “near-threatened”, primarily because of habit fragmentation and other concerns.

We also encountered the Pampas cat before. Because there has not been much study of these cats, their conservation status is not officially listed. As one can tell from the photo, it is a somewhat heavier looking cat than many of the other species. Little is known about its diet or hunting habits. Despite being named for the Pampas, their range extends far beyond its geographical boundaries.

For more information, please visit the ISEC website.  In our back yard, the Felidae Conservation Fund is also involved in wild-cat studies around the world, as well as close to home with a study of Bay Area mountain lions. Other organizations involved in cat conservation include the Feline Conservation Federation, and the Cat Specialist Group of the World Conservation Union.

Weekend Cat Blogging #306

Luna inspects the equipment for the next show during a recent practice session:

UPDATE: Luna just posed more regally next to the Nord keyboard. I think it’s a better picture (what do you think?).

The Nord Stage continues to be the main workhorse for idiomatic music, such as the jazz, caberet, etc. that may work its way into the performance.  The iPad (barely visible here) will provide the experimental counterpoint.

And here is Luna with some of the “analog” instruments:

The prayer bowl will be part of the show tomorrow, but the toy piano and tablas probably will not.


Weekend Cat Blogging #306 is at Pam’s Sidewalk Shoes. Check out the great close-ups of all three cats.

Weekend Cat Blogging #305

In the midst of all the other excitement going on, we at CatSynth are once again hosting Weekend Cat Blogging.  Honestly, we’d just like some extra time to rest, but we honor our commitments and are ready with our “WCB Street Sign” and this post.  And of course we look forward to seeing weekend feline friends old and new.

To participate, leave us a link to your cat-related post in the comments below.  You can also tweet us @catsynth with the hash tag #WCB.  We’ll add you to the round-up.  (Note that this week’s round-up will be a bit more sporadic and delayed given my focus on Open Studios this weekend and next week’s performance at the Marin Headlands, but it will be there.)

And so let us get on with the round-up.

It is usualy Jules who joins us from Judi’s Mind Over Matter, but this week it is Vincent who is featured.  It looks like he is enjoying some affection.

Arthur from Gattina’s My Cats and Funny Stories approves of a litterbox to have elegant surroundings.   As for us, we like the clean straight lines of the garden path.

It’s Caturday at Catsparella, which is when they feature a feline from one of there readers.  This weekend it is the aptly named Nosey Rosie, a cute tabby with an inquisitive nature.

There is some good news at The Chair Speaks, as Cinders is doing much better at recently being ill.  Here we see her resting in an airplane pose on newspaper and giving her thanks to all those who sent healing thoughts.

Speaking of newspapers, our friends at Animal Shelter Volunteer Life share the news that the well-informed newspaper-reading cat Conrad has been adopted.  They also list many other cats that have recently found their new homes.

Trees abound at Life From a Cat’s Perspective, where Samantha and Clementine interpret this week’s Photo Hunt theme of trees. They are also celebrating their 4th Blogoversary and we wish them well.

Over at Team Tabby, Moe says “This is what we do on Sunday“:

That sounds to us like a great way to spend a Sunday.

Naps are also good after a grooming session, as demonstrated by Luna and Zulu in their post :

They have the most amazing coloring.  It almost looks like one is an exact grayscale copy of the other.

Over at Pam’s Sidewalk Shoes, Coco reminds us to take time to smell the roses…err, tulips.  Something we at CatSynth need to keep in mind.

There are certainly times when we feel like this:

Check out the full size version from Kashim, Othello, Salome and Astrid at PaulChens FoodBlog?! for a cute image, even if “nobody’s home.”

At Whiskey Tango…Hello!, Allie and Chloe are showing off their better sides.  Readers can judge for themselves.

Finally, we have Meowza enjoying a nice day outside at Mind of Mog.

He stays happy and content via “canned kitty food, Temptations, mousies and lots of love.”

That concludes the round-up for this week.  Thanks to all who participated!

Weekend Cat Blogging #303: Red Stripe

Our busy schedule here at CatSynth continues unabated, with preparations for a second photo event in a couple of weeks and a new music project that requires quite a bit of practice.  Yesterday, instead of the usual Saturday morning Weekend Cat Blogging, I pulled off the cover of the Nord Stage keyboard to practice, and dropped the distinctive red dust cover (everything related to Nord keyboards is bright red) on the edge of Luna’s beanbag.  But that didn’t in anyway discourage her in anyway from curling up to take a nap – indeed, the dust cover almost looks like a brightly colored blanket.

It’s amazing how Luna can nap through just about any type of music.  This morning it was songs by the Cardiacs – a little different than our usual fare, but fun and challenging. You can get a taste for what this sounds like (and what Luna is putting up with) below:

Then again, it can’t be more challenging than some the very artificial experimental sounds that she hears living here.

Weekend Cat Blogging: Video and photography

For Weekend Cat Blogging, we present another video of Luna looking out the window.  She is exciting about something she saw and is chattering away.  There is also a very cute expression about 30 seconds in.

Yes, I have quite a few videos of Luna chattering or “window-hunting.” It’s in part because it’s one of things that makes me want to record video rather than take still images. There is no time to edit this down, as I am busy preparing for the photo show next week. Here one can see one of the featured prints being prepared, as Luna shows her disdain for the whole process.


Weekend Cat Blogging #302 is being hosted by Samantha and Clementine at Life from a Cat’s Perspective.

Carnival of the Cats will be up this Sunday at Pet’s Garden Blog.

Weekend Cat Blogging 301: A Sad Day

March 11 was a sad day.

It is with a heavy heart that we say goodbye to our friend Mickey.

As mentioned earlier this week, he fell very ill and passed away on Friday. He (through his mom) first visited us in late 2007, and they have been regulars on our site ever since, as likely to comment on experimental music shows and photography as Luna’s feline antics. And in turn, we enjoyed getting to know them better through their site. Our thoughts go out to Mom Nancy and the rest of the family today.


We have been closely following the tragic events in Japan after the earthquake and tsunami. Images such as these are heartbreaking, and our thoughts are with the people of Japan right now. While every year brings multiple huge disasters, when it happens somewhere you have visited or affects people you know, it hits harder.

Our friends at Cats of Wildcat Woods have compiled a list of relief organizations. The Red Cross is always a good place to start, and now you can donate via text messages.

There is no information currently on Tashirojima, or “Cat Island”, which is off the eastern coast of Japan in Miyagi Prefecture, near epicenter of the earthquake and tsunami, but the fear is that the island was lost.

Weekend Cat Blogging #300: Return to Normal

Luna looks on at the jumble of furniture, on which the dotara is sitting post performance.  I actually like the geometric formation of the tables pushed together during the construction, and the contrast of the curved musical instrument.

The big concert is now over and done. It mostly went quite beautifully, except for one technical flaw that disrupted the final piece (more on this in a later post).  The construction is also now done.  So we are looking forward to life at home returning to normal.

We now have the time and opportunity to put the apartment back together, and do those mundane but necessarily things that make up normal life. Oh, and to relax and enjoy a little down time.  At least until the next big creative project begins.  I think we will be starting on Tuesday.


Weekend Cat Blogging #300 is hosted by Mog and Meowza at Mind of Mog. Like us, they seem a bit dazed.

The Carnival of the Cats will be hosted tomorrow by Nikita and Elivra at Meowsings of an Opinionated Pussycat.
