Here is another fun geeky LED watch, which makes it confusing to tell the time, the Singularity LED Watch.
The Singularity LED Watch features a funky display with red and yellow LEDs, it displays the time and date in vertical and horizontal columns.
Tap the display button on the right side of the timepiece and watch the screen light up. In Time mode, the vertical column represents hour information in binary code. The horizontal row represents minute information also in binary code. In Date mode, the vertical column represents the month, and the horizontal row represents the day of the month, in binary code. You decide whether you want the watch to display the time randomly (every 10 minutes or so) or only show the time when you tap the button. How’s that for c as in e=mc squared coolness?
The The Singularity LED Watch is available for about $22 from Chinavasion.
