From what I can tell, very little is actually *described* in the
Milkdrop documentation.

Yeah, you can do all kinds of really funky stuff with systems of
differential equations, and the graphics hardware is pretty much
designed for this type of number crunching.

I can't imagine what the possible security risk could be...

Oh, yeah, I get how a graphics card works. What I can't figure out is
how some of the effects that Milkdrop generates are mathematically
possible. Figuring out the math is the hard part; actually making the
hardware do it is usually quite simple.
