I found a list of some cool Cross-breed Animals. Its got some I've never even heard of, like a Wolphin (Whale/Dolphin) or a Cama (Llama/Camel)

Homebrew 3d Scanner. Pretty cool 3d scanner they're working on. It uses a laser and legos, what more could you ask for!

Pretty cool R/C Shooting Battle Tanks.

Entertainment androids. Even Sega is making robots now!
