Woot's PG-13 filter won't allow sex, probably won't allow drugs, and is liable to cut blood (but not always).
There have been at least two one-ink derbies already, though that's been tied with other restrictions as well. Independence was one ink on red, white or royal blue, and we just had a black-and-white derby. 
The object of the inorganic derby would be *no* depictions of living things - artificial, fantastic, or otherwise. No zombiefied bunnies, no animatronic birds, no circuit-board trees, no anthropomorphic cars or paint cans, etc.
Sex Drugs and Rock& Roll would prove an interesting challenge to the artists, imho, if they were required to stick to both the theme and woot's PG-13 guidelines. The same with Blood.
I'd forgotten about the limits on the independence derby. Smack me in the face with a chainsaw for being unoriginal.
