That prototype is fucking cool.
I love this. It would bring so much power to working with "non-designers" in workshops, paper prototyping, etc.
Imagine getting printed pieces like legos and building a feature with your hands.
I'm so inspired.
Although it's hard to implement something like this for design in general, the idea seems really cool. I hope they expand on that and bring it to us to play with. I would for sure!
