Michael42er has been up to his tricks again! This time he's been modifying one of the paper animations from the www.flying-pig.co.uk website.

In its original form the exercising fool was powered with a simple push rod. Michael has cleverly added a crank to the box and then linked two of the models together.

He's also created a YouTube video which you can see here:

Nice one Michael, I can't wait to see what you come up with next!
