I finally returned to a 3-d random walk sketch I set up in Flash a few months ago. Happily, Papervision3D now reliably initializes the graphics context and actually renders the cubes inside the flash player (I downloaded the latest Great White and patched my code over tonight).
The cubes bounce along on a random trajectory and fluctuate to the music. Michael Lengel, aka mlerin , provided the sweet audio tracks.
Interact with the walking cubes.
