Cool . One[1] suggestion though: Your randomizing function could be altered so that it only shows every rig once. As it is now, I can get the same picture several times in a row, before I get a picture I yet haven't seen. It would be good to also have a "back" link so one could go back to a previously already seen rig. Also a comment form field for each rig would be nice. Oh, and urls that could be copied as direct links to each rig.
