If you’re on a Mac running OS X, go download Konfabulator, one of the great cool programs to emerge in a long time. It’s a framework for running widgets that can do just about anything: display the current weather, update stock quotes, or even play games. Konfabulator widgets appear on your desktop, and can show up just in the Finder or on top of other programs.
But that’s not the freakin’ cool part yet. Now, download LyricScraper and activate it. As you’re listening to iTunes, LyricScraper goes out to the Web and fetches the lyrics to the song you’re listening to. If it doesn’t find a match, it displays a list of close guesses. Wild!
