Hi Stephen,

fft processed to identify some frequency information - no beat detection yet.

- keyboard/mouse events
- osc network messages (http://www.cnmat.berkeley.edu/OpenSoundControl/)

The console and editor are ways to write Scheme in an integrated way with
the graphics  - but you don't have to use them, it works inside DrScheme
and Mred - I'm still putting the finishing touches to a nice interface for
this, but it works in a raw form now (by rendering into a Mred GL

On the inside it's really a game engine, with a scenegraph for storing
primitive geometry and state information hierachically. It supports a
range of primitive types, polygons, NURBS, implicit surfaces and particles
are probably the main ones. It also integrates some other things like ODE
for rigid body dynamics, and GLSL shaders for GPU programming.

Yup - I also use OSC message output to use it to drive a soft synth for
this sort of thing: http://www.pawfal.org/al-jazari/
