CHISENBOP TUTORIAL - Andy Harris
http://klingon.cs.iupui.edu/~aharris/chis/chis.html
Andy Harris, a computer science instructor for Indiana
University/Purdue University - Indianapolis (IUPUI),
originally wrote the Chisenbop tutorial to compare this
finger arithmetic method with the way computers do
calculations.
His Streaming Media Lessons, which require the free Real
Media player, begin here:

SNOW CRYSTALS - Kenneth G. Libbrecht
http://www.its.caltech.edu/~atomic/snowcrystals/
This site is all about snow crystals and snowflakes, and how
these remarkably complex and beautiful structures appear,
quite literally, out of thin air. The many facets of snow
crystals are described in these sections:
- Natural Snowflakes
- Designer Snowflakes
- Snow Crystal FAQs
\|/
CRYSTALS - S. Alejandre
Students studying polyhedra enjoy seeing the structures as
they occur in the real world.
- Crystallography
- Systems of Crystals
- Paper Nets
