Have you been to Google's home page recently? Do it, you've got less than 24 hours to check out its guitar-inspired doodle celebrating the birthday of Les Paul. The "Google" script is highly interactive thanks to a combination of JavaScript, HTML5, CSS, and even Flash (providing the audio). Click the compose button at the base of the second "g" and begin recording your own 30 second tribute to one of music's most innovative pioneers using your keyboard to play specific notes or mouse for virtual strumming. Unfortunately, the recording and sharing aspect appears limited to US Googlers. Impressive stuff from a typically impressive company.

Update: After holding the doodle over an extra day, it looks like Google has given the tribute a permanent home, like Pac-Man before it.
