Video Feedback

Last night I pointed my webcam to the TV and I was surprised by the complexity of the images generated. Later I found out this is called video feedback, and with the help of a mirror you can create colorful dancing fractals. This phenomenon, which essentially is a non-linear 2D map iterated at very high speed (30-60 Hz), has been extensively studied by mathematicians and physicists.

Modular Origami



Making modular origami (or unit origami) is a repetitive task that any properly trained lab monkey could enjoy. As the name suggests, modular origamis are built from modules or units, i.e. they are composed of identically folded pieces of paper that join together without glue. Sort of lego with paper. I've built several geometric models (polyhedra, stellated polyhedra, intersecting planes). I'll post some pictures soon. In the mean time, here are some modular origami sites:

Flash Party 2004

A week ago it took place the Flash Party 2004, a 3-day exhibition of demos, intros and digital art with live shows and contests.

I went to the party on Saturday after visiting León Ferrari's exhibition. Some wonderful demos and intros were shown. Mindprobe did a trully amazing psychedelic trance live set. Panoramix (one of the members of Mindprobe) won the first price in the demos contest, and Sobame got the first price with his retro intro. 8GB did a live audiovisual set (music performed with weird gadgets such as a Commodore-64 and a GameBoy). And some guys did a live juggling/lights/music show, naked and wrapped in nylon... bizarre. Too bad there were no female monkeys on stage. The demos, music and other works are available for download from scene.org

León Ferrari

Last week I visited the Recoleta Cultural Center (Centro Cultural Recoleta) in Buenos Aires, and I had the opportunity to see Leon Ferrari's retrospective exhibition. The day before, some Catholic fundamentalist attempted to destroy one of the works (I think it was an image of the Pope in a jar full of condoms), but fortunately he was detained by the police. Pigs protecting art, that's quite rare. I saw figures of Jesus in a blender and a toaster, the works with excrement, and the famous Jesus Christ on a US bomber (which León made in protest against the Vietnam war). He calls for the abolition of Hell, which essentially is a torture chamber set up by christians to punish non believers for all eternity. Infinite justice, sounds familiar? I enjoyed very much the works that attack fascism and criticize the dark side of christianity, but the works that I liked the most were the heliographs and some abstract sculptures built with iron wires.

If you feel unconfortable with this expression of art, you may want to read León's writing Regarding Torture. More at León Ferrari's web site, and at his blog.
