Build a Mechanical Hand

Build a mechanical "hand" using materials you find around the house. You can create moving fingers, claws, or design a grabber type device (like tongs). If your "hand" can actually pick something up, that's even better!

Here are a few websites with ideas to get you started. What other designs can you think up?
