Binary Clock

With the closing of all the Discovery stores in the St. Louis area, there are some great deals to be had as they liquidate their inventories. As a result, my geek cred got a boost with this cool Father's Day gift.

The display can be switched from Binary Coded Decimal (BCD) to straight binary, 12-hour or 24-hour format, and the blue LEDs have three different brightness settings. If you're looking for the perfect gift for your geek, find a Discovery store near you.
