- Paper models for building Ammann rhombohedra. There are two types of Ammann rhombohedra - one skinny and one fat.

Ammann rhombohedra tile space quasiperiodically and can be viewed as the three-dimensional analogue of the Penrose rhombus tiling.

- Koch snowflake

- Dragon curve

- A collection of recursive trees with sligthly different branching rules. This type of branching rule produce shapes similar to cauliflowers. The tree at the bottom right has a rule with a small random component.
