After all these years, you'd think we'd have the art of telling time perfected by now. First we tried Stonehenge, and then the sundial. At some point down the line, we attached wooden birds to the thing, and eventually wrist straps and calculators. Now, six years into this new millennium, comes the Lightmare Watch, so named because attempting to tell time on the thing is a bit like showing up to Algebra class in your underwear. According to the product's website, 'The four small LEDs at the center represent the single minutes between each of the five-minute increments, and the two very small dots in the bottom center represent AM or PM.' Put simply, the thing makes telling time an active sport, assuring that you miss every train, plane, and important meeting, as you were too busy attempting to decipher what looks to be a poor man's Lite-Brite. $149.95 seems like a small price to pay for countless hours of frustration and missed appointments.
