There are lots of vids on youtube where people show their lego stop motion animations. It’s kind of cool. I’ve made up a python script which makes something like that.
There are two vids. (Just hit play triangle 
The rest of interface is in russian)

I don’t think it’s clearly seen, but the script makes different blocks (with one pin, a square with four pins and rectangle with eight pins).
So. Now I’m thinking of some concept video starring lego blocks =)
