Fantastic Fysics Fun

Just wanted to share this online game/puzzle with you since Wolfie has been playing it non-stop for the last five hours (seriously). Fantastic Contraption asks players to build a machine that will move a red ball from the left side of the screen to the goal on the right using directional wheels, wooden poles and caterpillar tracks, among other things. You can save your contraptions and look at others' contraptions for ideas. Way cool!
