Whistle to control your computer

IBM developerWorks offers instructions on how to interact with your computer by whistling -- that's right, whistling.

Use Linux or Microsoft Windows, the open source sndpeek program, and a simple Perl script to read specific sequences of tonal events -- literally whistling, humming, or singing at your computer -- and run commands based on those tones. Give your computer a short low whistle to check your e-mail or unlock your screensaver with the opening bars of Beethoven's Fifth Symphony.

This method isn't for beginners - it requires modifying several scripts and it takes about an hour to complete.
