A decent number of game educational sites, including mine: http://eMusicTheory.com http://eMusicTheory.com -- in a small Java applet, I can process MIDI and audio input, assemble digital audio on-the-fly for output (or use MIDI, but they stopped bundling the sounds), animations, etc. within pretty much any browser starting with IE5 or 6. There's nothing else as powerful AFAIK. Java's security problems seem like they'll kill this off, unfortunately.
