No gold at the end of this rainbow

USB-powered devices are dime a dozen, and some of them are pretty useless, while others have a more practical ring to it. Take the Rainbow Pen Holder Clock from Brando for example. It is actually a pen holder with clock functions, displaying all the necessary information such as time, data, month, day, stopwatch, and calendar. Different colored lights will illuminate the LCD at timed intervals to keep you entertained once you’ve completed your daily Minesweeper run. This workspace accessory can be powered by a trio of AAA battery or hooked up to your USB port. It currently retails for $15 a pop.
