iTunes Now Playing
I am playing with this little application for OS X called "Now Playing". You can find it on MACOSX Hints.
What it does, when run a long with iTunes, it will generate a .png file and upload it to your ftp server (.MAC account, or WebDAV). You can see this at the bottom of the page here. I thought it was kind of neat. And plan on using it when I listen to music with iTunes on my laptop.
