Tiling paper models
 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 threedimensional analogue of the Penrose rhombus tiling.
 Paper model for building a type of rhombohedra studied in

 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.
