Aaron Dayman has ventured into the uncharted (for him, anyway) waters of Bionicle/Technic building, armed only with a seed part (the long gunmetal panels), and created this Scrapmetal-Bot Scorpion. I like the combination of gears and tubing, especially on the tail.

ToM has put up some new pictures of his White Makuta creation. My favorite part is probably the warhammer.

Primus's Call of Cthulhu uses inverted tires and tentacles to make an excellent squiddy sort of head. The rest of the diorama isn't too bad either. You can check out his short comic leading up to this creation if you're into that sort of thing.
