The eventual takeover of mankind by machines comes one step closer with the creation of this giant robot hand. It was built by untrained volunteers for the Robodock festival in Amsterdam last month, and is actually capable of crushing everything from shopping carts to small vans. The hand itself is 25 feet long, weighs about 5,000 pounds and was built from scrapyard parts including I-beams for the fingers and a digging machine truss as the forearm.

The coolest part is that it has an immersive interface. It actually works as an extension of the user's real arm!
