“I like to design complex paper sculptures by combining mechanisms,” says Paul DeGraaf.
They're absolutely amazing! A playable electronic keyboard!
Here's a couple of wonderful IMGUR galleries where Paul showcases his absolutely beautiful mechanized papercraft sculptures: Part One, and Two.
From Paul:
I like to work with paper and create mechanisms that are complex. It’s lots of fun and there’s a lot of problem solving involved. Some may think it boring or a waste of time but for me it’s like playing with paper LEGO.
Just incredible.
