R2D2 was on to something. Think easier speech recognition with reduced error rates:

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 your screensaver with the opening bars of Beethoven’s Fifth Symphony. Whistle while you work for higher efficiency.

This ought to be nostalgic for all of you who remember trying to whistle a successful modem handshake sequence. (Someone please tell me I’m not the only nerd in the room who did this for kicks.)
