When you need a new alarm, don't settle for the standard clock. Instead, try making one out of Lego--one that happens to tell the time in binary.
Lego modder nxt1engineer made this clock from Lego bricks and a Mindstorms NXT kit, and placed white markers on rotating spindles to indicate the time. You don't need to know binary to read the clock, either; you just need to know how to add. Of course, you'll need to be quick-witted to reel off the seconds, but at least your not-so-geeky friends will be impressed!
