Mine's not quite as cool, but here are a couple renders:
Ye Olde Sierpinski:
Some fancier ones:
Other things I'd like to do with it:
- HDR tone mapping - right now it's just a log density effect
- Gaussian blur/glowy stuff
- Kernel density estimation - to help smooth out the noise
This all runs realtime (a pretty reasonable framerate on my 6600), so eventually I'd like to get some animation going.
