Had your fill of binary clocks? Check out this analog binary wall clock, which combines traditional clock technology with the computer science nerditry that ensured you never got laid in high school. The clock looks like an actual clock, but instead of numbers or even roman numerals, you get the binary representation of 1 through 12 instead.
This costs $40, so you may be better off going to a garage sale, buying a clock for $2, and making your own binary clock out of some construction paper. Better yet, make one that just says "BEER" twelve times. Heh, beer o'clock.
