Brown University Engineering and Visual Arts lecturer Ian Gonsher’s Generative Construction Toy is a set of snap together shapes that you can cut out on a laser cutter and use as building blocks to design and build compound three dimensional objects. It’s like an evolving desktop fab version of tinker toys or LEGO, but more organic. What’s most interesting about the GCT is that you are encouraged to modify and create your own shapes through an iterative process of design and play.

If you have a laser cutter or are willing to spend the time cutting the shapes out by hand, you can download the GCT outlines from Ian’s site. [Thanks, Ian!]

I make cool stuff and write about other people making cool stuff on If you have something you think I should see, send me a tip.

    Looks interesting, but one would think he could post the design in a more accessible format than Adobe Illustrator.
