I should hardly admire more if real stars fell
and lodged on my coat."

Designer Snowflakes

x11a.jpg (4964 bytes)    We grow our own "designer" snowflakes in the lab year-round, right here in sunny Southern California.  It's part of our ongoing research into the physics of crystal growth and pattern formation.  View three generations of laboratory-grown snowflakes at our Designer Snowflake Galleries, or watch some Movies of growing snow crystals. 

Snowflake Physics
