The problem might be an inferior school laptop, it is only a 32-bit machine.

When I try it on my desktop machine (Mac G5 quad-core 64-bit OS 10.4.11) it
seems to run, but I still get no good image. I have to use 10.6 because the new
beta only runs under 10.5+, apparently.

maybe it's something with beta 35a specifically, but I can't think what.

as for the attractor, I got the math from this site:

it's the Rampe3 Attractor.
