I am in love with The Institute for Figuring. If you’re at all interested in geometric art, tessellations, chaos, fractals, or really anything- you should become a member. It’s highly worthwhile.
From their website:
The Institute For Figuring is an educational organization dedicated to enhancing the public understanding of figures and figuring techniques. From the physics of snowflakes and the hyperbolic geometry of sea slugs, to the mathematics of paper folding and graphical models of the human mind, the Institute takes as its purview a complex ecology of figuring.
It’s like someone took EVERYTHING out there that I find interesting, and wrapped it up into a non-profit with a cool website, publications, and speaking events! Fantastic stuff.
To whet your appetite, there’s a rather good article on mathematical paper folding on their site currently:
