Animated Engines
Some of the animations are rather large, so you may need to allow a few extra seconds while each page loads. These pages use animated GIF files, so they require a fairly recent browser -- any but the oldest browsers will do. If the main illustration at the top of each page isn't moving, you'll need to update your browser for the full effect.
