polyrhythms are basically multiple rhythms in differant timings which cross each other every so often. they can be very nice.

for a simple example think orbital "when time becomes a loop" (the vocal version on the brown album - imagine the two vocal samples are a rhythm and there you have polyrhythm.
Thank you sir for the musik education. I now understand about poly rhythms. Yeah and it's cool stuff Steve. I like most of the voidloss stuff you've done. Although I still don't think it's all that odd.
