This beautiful enamel pin badge features the recently-discovered 'Einstein' (hat) aperiodic monotile, in all the colours of a beautiful rainbow. The tile can be used to cover an entire infinite plane in such a way that the pattern will never repeat, and was one of the first shapes discovered with this property. Show your pride in aperiodicity by pinning it to your bag, lanyard or clothing item (or anything you can pin stuff to really).
Enamel pin badge measures 3cm, with a single pin fixture on the back and a rubber pin cover. Design by Jamie Gallagher, who also sells a selection of other fun scientific pin badges. We also sell Jamie's 0.7734 calculator pin badge!
