Are you a binary horse — somebody who can look at binary and convert it in your head rather than going to some website that will calculate it for you? If you are, then you need a binary clock, which will keep the connections in your brain snapping whenever you need to know the time.

Each column on the clock represents a different part of the time, with blue LEDs turned on or off to represent a given number. In the picture I’ve provided here, the left-most column represents 1. The next column represents 0. The third column is 4. The fourth column is 8. The fifth column is 3. And the right-most column is 6. Put those numbers together, and you get 10:48:36.

How long did it take you to figure that out? Took me about 10 minutes — using an online binary converter. I’ll never be able to use a clock like this, because it’ll guarantee my late arrival to any appointment in my calendar.

According to the description, you can run it in 12-hour (and look out the window to know which half of the day you’re in) or 24-hour mode.

In idle moments between jobs, I grab a magazine and read an article. Perhaps this little product would be a nice change of pace. Hmm. Or perhaps I could take up Spider Solitaire.
