We dig the sparkle of this color-changing USB Rainbow Pen Holder Clock. At a size of 110 x 73 x 76 mm, the clock features 4 different flashing modes and includes an LCD alarm with calendar, which displays date, month, day, and time in a 12/24 format. It also works as a stopwatch and can be powered by its USB or 3 AAA batteries (not included.) Add to that the affordable price of $15.00 and a BeeGee tune and you and your cronies at work can have a quickie disco party during your lunch hour.
