tessellations

In ninth grade, I had an obsession with tessellations, which was probably the only moment in my educational history I can say I understood anything mathematical. I painted an entire wall in my bedroom with a giant wave tessellation pattern in aqua and royal blue. If only I'd kept a photo...

I found some amazing paper tessellation sculptures today. Here's the link to them all. Here's an image of one!

I would love to learn how to make these.
