So there's this nice device called N900. And a cool user interface video:
The song in that video is GRUM - Go Back (Le Castle Vania Remix), an energetic tune, freely downloadable from the net.
Lastly, here's a less than 30 second excerpt of that song, so that you could, for example, enjoy it in your cellular phone :)
Update: You can get another, more official N900 ringtone and message alert tone from links on Nokia Europe pages.
