I think this is the coolest clock I’ve seen and most visitors won’t even know it’s a cool time piece but will think it’s just some colorful high tech ornament. It works like a digital clock where the is one colorful block of squares for each digit that you would see on a digital clock. The number of square that light up tell you the time. Not the best description I know but look at the picture and I’m sure you’ll work it out .

Like tons of cool stuff this also is available from ThinkGeek.com
