The Einstein hat does repeat periodically… on a cylinder!?

Months ago you may have seen the new shape that does not periodically tile (repeat) like most other shapes, in the plane. However, that is assuming an infinite (x,y) plane… What if instead of that geometry, we try building out a periodic cylindrical tiling?
