Tessellations+Topography+Symmetry

Art-related math (with a literacy connection...)

[] This is a demonstration of tessellations--how to make them.

[] A good introduction to topology--and has a neat demonstration of deformation

[] Another good introduction to topology--and a funny joke about topologists

[] Neat resources on symmetry (once you scroll past the advertisement)

Salt clay recipe:
 * 1 cup flour
 * 3/4 cup salt
 * 1/2 cup water
 * 1/4 cup cooking oil
 * Food coloring

[] Tessellations and M.C. Escher. Also has ways of making complex tessellations. This is an excellent resource.

[] Snowflakes are radially symmetrical and here is a webpage on the science of snowflakes--how they are formed.

[] Kaleidoscopes take asymmetrical items and turn them into radially symmetrical images. This page allows you to choose asymmetrical elements and then you can see how the image becomes radially symmetrical.
