The shirt reminded me of one of my first posts - - Toy Lab:
Happen's Toy Lab is a unique outreach of Happen, Inc. that allows children (ages 6 and up) to create their own toys from our massive selection of “recycled” toy parts. Choose any seven pieces, then fit and attach the parts with the help of our specially-trained assemblers. In less than an hour you will have invented your very own, one-of-a-kind-in-the-whole-wide-world toy!
Here's a gallery of toys created at Toy Lab.
