There appears to be a rash to retro gaming products about at the moment (probably in preparation for the approaching festive season, although we are loath to mention it just yet), including this Pac-Man Alarm Clock from Paladone.
As you can see here, the clock consists of a giant pac-man with a digital clock inside his mouth. The alarm uses authentic sounds from the original game, which should be irritating enough to get most people out of bed on time.
It is available to buy online from Comet for £29.99.
