I realize the pulley system shown on the shirt isn't entirely accurate. When I tried a more realistic system, the composition on the shirt didn't quite look right. It would have pushed the mice to be down on the belly of the shirt, and the focus of the shirt would have been mostly pulleys. So, while it would have been more correct, it would have looked a bit less appealing to the general person (as opposed to physics/pulley fans).
I struggled all day Saturday with how to make a real pulley system work, which is why this entry is so late ^^;. Sorry it's kind of flubbed. I did find a few references and cartoons about pulleys that showed similar displays of them as I have here. I was hoping it would still get the point across about the neatness of pulleys.
