I spent about 10 minutes messing with the tools and reading the information about it. It was very easy to follow along with and was pretty fun. I think this would be a good tool for someone to use.

I spent a good half an hour playing with the materials. The kali wallpaper patterns were very fun to play with. I made hperbolic triangles, looked at the lorenz simulation, and made different patterns and wallpapers. I read the mathamatical explinations and formulas that were used to make the simulations, but I didnt see one for the Kali patterns. Under the link it explains that the patterns are created illustrates the planar symmetry groups, however when I click the link there is not explination to WHAT planar symmetry groups are, only instructions on how to use the program. The simulations will help people understand the mathamatics covered, with explinations and interactive tools. Its great for someone who does better with visuals than with written down facts. It was extremely easy to use the materials you wouldnt have to read all the instructions, just click and you'll figure it out.

The link goes to a number of geometry applets. ?Hyperbolic triangles? is about the hyperbolic plane. A definition of the hyperbolic plane would be nice as a start. Cute applet. Certainly a nice demo for hyperbolic geometry.
