  • 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.

    From Alex Ross: The Rest is Noise:

    “According to the notes in this new Naxos release…the photograph was taken on June 28, 1925, two days before the completion of the First. It comes from the DSCH Archive in Moscow.”

    Have you encountered any other noted composers with cats? (John Cage is a well-known example.)

  • 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.

    More music on umop.com! Background music: “O Face” by Parallax.

    Get a look inside Analog Heaven Northeast 2011, an annual meetup for synth enthusiasts on the East Coast. Every year we bring a selection of irreplaceable electronic gewgaws from our respective music studios (you can spot my Customsynth Rolands in there somewhere) for each other to admire. Great turnout this year! We even had a visit from the God of Catsynth, apparently.

    More from this series in coming days. It is exciting to see the OP-1 in action (particularly being played by a cat). You can see my preview of the OP-1 from last year’s NAMM show.

  • 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.
