GARRET LISI ON HIS THEORY OF EVERYTHING

Physicist and surfer Garrett Lisi presents a controversial new model of the universe that -- just maybe -- answers all the big questions. If nothing else, it's the most beautiful 8-dimensional model of elementary particles and forces you've ever seen.

MOLECULAR SHAPE AND VSEPR INFORMATION

Very cool rotating 3-D shapes. Even gives the option of buying 3-D glasses to really get a good effect.

Drawing Structures:
I thought this was really amazing tool. You can draw the shapes yourself. I had to play with it a little bit before I understood how to use the program they are using.
