Friday ~~Flash~~ Java Fun - 'Building Houses With Side Views' Entertaining Java game/exercise/doodad. A nice little Java game/exercise/doodad where you place blocks in a three-dimensional grid so as to match three different projections. Then, for maximum points, you try to find the minimum number of blocks that will solve the problem. Twenty puzzles in all. Perfect for wasting half an hour.

...the models live in the curved space of the hypersphere...

Here are some beautifully rendered views of polytopes, and a few more. The rendering program, Jenn 3D, is free and downloadable, (OS X, Linux, Win) and includes some really dazzling fly-about and camera effects as well as tons of high-dimensional models to explore. There's also a mind-boggling possibility of playing Go on boards in projective space. Via the Math Paint blog, which leads to other interesting places...

Math is congruent with fun!

You have spacial skills. Apply them in Building Houses 2, on mathsnet.net. Or freestyle in Building Houses 1. Or at night! Oh and also there's like a hundred more puzzles over there too. Some java required.

Minimal surfaces in 3D (red/green, or stereo pairs), with rotate and zoom. If you want to go beyond the eye-candy aspect, here's the obligatory Mathworld link, the classic intuitive explanation, and a raft of additional information. If you like eye-candy, don't miss the ray-traced minimal surfaces and these interesting, but non-minimal surfaces.
