I think (I could be wrong) but it's better to think of it as just one 
huge one-dimensional circular array (that wraps back to the start once 
you get to the end). The different seeds will just get you started at 
different points in the array.

Using "frame_number" rather than "clock" would be better, as AFAIK the 
seed function takes the integer part only.
