Current favorate: Quasiperiodic self-inducing (seilf-similar) structures. Here are some nice pictures:
First: Minimal Pisot number tiling, Second: sofic Pisot Tiling
You find different ones in Japanese side. This research has close connection with ergodic theory, symbolic dynamics and Diophantine approximation.
