Mathematician Richard Kershner discovered this pentagonal tiling in 1968. Nearly 50 years later you can now 3D print it as a bracelet for some serious geek bling.
This model 3D prints as a flat strip. Get a mug of very hot water and use it to heat and bend the bracelet to fit your wrist. It's easy!
