Syntonic Dentiforms is a demo (non-interactive program that shows realtime graphics and plays some music). I and a couple of my friends did it on our spare time for fun and experience. The demo was developed during Feb-Mar 2004. We took it to Breakpoint'04 demoparty in Germany, it got 6th place (out of 22).
Hey, it also won a scene.org award for "breakthrough performance" during 2004 year!
I did most of programming stuff, and a small amount of modelling/animations. The demo features:
Zip file here (6.5MB). Requires DirectX9.0b runtime and at least pixel shader 1.1 capable 3D accelerator (but looks better with ps2.0).
