Bluetooth Dongle + Mobile Phone + Ubuntu PC = ?

American science fiction author Thomas Disch once said that Creativity is the ability to see relationships where none exist. So be creative and think about what to do with a USB bluetooth dongle from a broken Microsoft keyboard, a Sony Ericsson K770i mobile phone, and a PC running Ubuntu Linux.
I guess you all immediately came up with the same idea as the guy behind EdgyRootStudios and would use the mobile phone as a remote control for your desktop PC, wouldn't you? And the best thing of all, it just works. Impressive!
