My memories of this are so vague that for a while I thought there was probably no point in posting about it, but then I figured I might as well put it out there. Sometime in the mid to late 1990s I saw a brief segment of a television program which featured claymation figures on what appeared to be a long, twisting conveyor belt. As I recall, the figures were incredibly basic, just humanoid in shape and lacking any features whatsoever. Kind of like these:
I think they were dark pink in color though. I don't know why they were on the conveyor belt. One thing I am almost certain of is that it aired on PBS, and it was during the evening and didn't seem like a kids show. There was music playing and I don't think there was any talking.
That's basically all I can remember, but I can see it visually in my mind. I may draw a rendition of how the scene looked and post it. The lighting was pretty dark.
