12 Piece Lego Mechanical Puzzle (Lime Time)

With a few basic pieces you can make this really cool mechanical (or interlocking or burr) puzzle. It's a challenge to take apart and to put back together again too!

I call this one Lime Time because it's made of lime colored bricks and the only 1x2 tiles I have, clock displays. 

To make this puzzle you'll need:
-1x1 tile (x2)
-1x2 tile (x83)
-1x2 plate (x84)
-1x2 brick (x47)
-1x2 brick (x24)

Make 11 of these

The "special" piece is pretty much the same as the other pieces except it has a chunk missing.
