Tessellation with Customizable Rotating Kites

This tessellation uses the kite with 6-fold rotation at one vertex and a 3-fold rotation at the opposite vertex, but makes the sides customizable.

1) Can you change the kite to make it look like something else? (An animal or bird or face or crazy creature?)
2) When you change one border, can you predict what else will change?
3) Why do the tiles fit together even after you change them?
