We then went wild buying shirts for the family, a sticker (stuck currently on the water filter in the living room), a mug which was supposed to be mine but which my son guards as a precious possession, and a giant wall tapestry to hang in my son's room. I actually wasn't sure all of those were going to come out, but even on the sticker, you can make out the individual cells in the more complex designs. Anyway - we enjoy these things on a daily basis.
We're kinda a bunch of math geeks. My husband and I both have masters degrees in the field, and our son, I guess, is a demonstration of what you can accomplish with selective breeding. ;) We have a lot of mathematical curiosities around the house, most of them homemade - penrose and hat tile fridge magnets, klein bottles, constant width solids, representations of projective tuning space. You know, the usual.
Other enthusiasts in the (very niche) space enjoy seeing the graphic. Since the time of creation, math has advanced, with these no longer being the smallest or best examples of some of these loops. This is exciting for all of us - the advance of mathematics is usually not this accessible. :)
