Music Animation Machine

This is very cool. This small program will play back any MIDI music file and display any of 14 different animations based on the musical content of the file (things like note values, intervals, part movement, and others). To use the free Music Animation Machine MIDI Player, you have to download, unzip, save, and run it on a PC (the .exe file runs directly - it doesn't require an installation program). Windows includes a default wave-table synthesizer, so it should work on any Windows machine with a sound card (if you have hardware or software synthesizers or other MIDI playback devices, it should also work with those).

Many of the animations look best when playing classical music which tends to have more distinct moving musical lines than most popular music, and it comes with several sample classical pieces. You can find tons of classical (and other) MIDI files all over the internet. Bach is especially visual (and sounds good too). The space bar starts and stops the playback.
