But then you have to calculate modulus for 200 or 320.

[tripzilch]

except the pixels are in a linear framebuffer, the fizzlePixel(x, y) function has a multiplication by 320 in it to calculate the address in the buffer.

so you could skip both the modulo and the mul if you go straight for obtaining a random shuffled framebuffer index.

unless maybe fizzlePixel does additional bookkeeping for some purpose.

Huh the original implementation seems to have a lookup table instead of that, interesting.
