So much to do.. I don't actually have Lego WeDo blocks, but perhaps you do, and you can use this. Use Up and Down to move. Turn Video on or off for obvious reasons. Use the Forward/Backward variable to go forward or backward. Use G and F to start and stop your creation. Great idea: Attach your webcam to a Lego WeDo car. Then, you can use the controls to drive around, and see where your car is going, as if you were in it! =D Yes, this would effectively turn into a spy car. XP
