Connecting an audio source to LEDs

Archived from groups: rec.audio.tech (More info?)

This is more of a general question but, is it at all possible to wire,
let's say, an iPod to a series of LEDs that you'd pick up at RadioShack?
Something along the lines of having the LEDs emit in response to the
music, similar to how a stereo's LED indicator will pulses in response
to what;s playing. If it is possible, how difficult (and costly) would
this endeavor be? Thank for any help you can give.
