They have some really cool (and very complicated) jigsaw puzzles  that I bought as gifts for my family. The Inifinity Puzzle is topologically a torus so you can infinitely tile it by taking a piece of off the left and placing it onto the right side.
I have a set of their coral coffee mugs  which I absolutely love, especially after toying around with my own reaction-diffusion based designs/art.

It would be so neat if it was easy to have script elements and inputs (sliders, knobs) as part of a design in Fusion 360 so that one could make interesting parametric geometries easy to play with.
