What happens when you cross a hexagram with a soap bubble and then ever so slightly mutate it. This minimal surface hangs from 12 linked semicircles. The connections between the top and bottom portions of the surface undergo a half twist, so the outside of the top is the inside of the bottom and vice versa.
Use it as an interesting but minimalist expression of your love for math, or just enjoy it as something smooth, shiny, and neat to hold in your hand.
