Fractals 2007
The winners of the Benoit Mandelbrot Fractal Art Contest 2007 proves that fractal art actually has evolved since the eighties.
Crayon Physics
Crayon Physics allows you to draw objects using the mouse and let them interact with each other (by rigid body physics).
As of now Crayon Physics can be tested as a downloadable prototype, but a more complex version is under development.
Update: Marker World is a similar themed game, strongly inspired by Crayon Physics.
Complexification
Jared Tarbell’s Complexification.net offers plenty of beautiful Processing-based art – most can be run directly from Java applets and have source code included.
4K Should Be Enough For Everyone
Kindernoiser (yep, weird name) is a a 4096 byte demo of 3D julia sets. For comparison the HTML for this page is close to 30 KB.
If you do not have a powerful graphics card, try the video linked to below.
Light synths
By coincidence I came across Jeff Minter’s company Llamasoft and surprisingly discovered that it was still going strong.
Jeff Minter, probably most famous for his somewhat… surreal C64 games (“Attack of the Mutant Camels”, “Revenge of the Mutant Camels” and even “Metagalactic Llamas Battle at the Edge of Time”), apparently has been hacking away on light synthesizers for the past twenty years.
His light synthesizers are complex visualization modules either music-controlled or driven by human interaction. And his latest incarnation, Neon, is actually used in the Xbox 360′s dashboard.
