So this is a demo to test lighting etc for ATI 3600 and 3800 series it is retarded in a fun way. If your system can hang its the most fun you'll have with a hair dryer.
If you system cant hang just watch the video. Hell watch the video demo anyway its got some pretty cool commentary on lighting. I suggest using the duel hair dryers.

Whut should be great at this since it involves playing with balls.
the most I got was about 1200 for time trial..took me bout an hr to get all 4000 in free play mode.
No hicups on my system which runs AMD 64 X 2 Dual core 5000+ with 4G ram... Retard strength FTW and ati radeon 3870 512
