Eric Haines reminds in a blog article the problems that arise when rendering a cone, which are surprisingly tricky for such a seemingly simple task. A discussion on the topic also spawned on Twitter.

From the Wikipedia article:
Gantz Graf is a three-track EP released by Autechre in 2002 on CD and 12″. A special DVD release was made available featuring the “Gantz Graf” video created by Alex Rutterford […].
The video features an abstract object (or an agglomeration of objects) synchronized to the sounds in the music as it morphs, pulsates, shakes, and finally dissolves.
Pretty old material already, but very worth watching as it is a reference in glitch animation style.
