Animation viewing in the frames environment is not recommended, due to the fact that the animations usually take up the whole screen. Trying to view the animation in a frame results usually in scroll bars.
Who wants scroll bars on a movie?!
Back out to the spin page and take the 'Animations' fork. Do not use your browser's 'back button'(command-[ on NetScape on Mac). Use the hyperlinked buttons. The animation resources are not cached, apparently, and backing out of a set of links causes the reload from the server, delayin g the backout process and necessitating a 115K file transfer. This sucks.

The animation pages are threaded so that all animations can be viewed in three sets in any order.

The next screen downloads 117K of graphic material(movies). Seventy seconds on my machine. Your milage may vary. A computer animation of a chemical reaction.

You must have Shockwave installed. Don't say I didn't warn you.

Abandon all hope, all ye who enter you have been warned.
