Although I've wanted a "Clock" like this for over 30 years and was looking for one at least 12" square, Beggar's can't be choosers.. I love this
Smaller Than It Looks Online

I purchased this gift for my boss - it looks pretty awesome in the photo, but when it arrived - it's way smaller than I thought. I didn't remove it from the packaging, but I did lift it and it feels very lightweight, which usually means poorly made. I am hoping that when he uses it, he'll like it, but from what I see right now, it's more appropriate for a kid.
I think this is really cool

We have had our binary clock for several years, and it almost always draws attention and comments. 'What's that thing?" is the most frequent question we get. When I try to explain the 1, 2, 4, 8 and the carious combinations of lights -- I get blank stares that seem to say, "What the heck are you talking about?!" Lots of fun! So happy that we bought one!

Binary Clock

These clocks use binary code—the language of computers—to show the time. After a few minutes' practice, you'll be able to read the time by adding the values of the lit LEDs in each column.


Put on a light show, confuse your friends, and exercise your binary-code reading skills with an alarm clock that doesn’t have any numbers on its display.

Lyle Morris, an electrical engineer, is the creator of the Anelace Powers of 2 clock. It uses LEDs to display the time in binary code, which is a method of representing computer instructions using 0s and 1s. The columns on the display correspond to hours, minutes and seconds, and each row is assigned a value. To calculate the time, you add up the values of the LEDs that are lit up in each column. (Instructions are included, and it's surprisingly easy to understand, once you learn the code.)

The display changes constantly as time passes, and it’s mesmerizing to watch. Lyle’s timepiece is elegant, a great conversation starter, and also educational. Using binary code to represent a familiar value, like time, makes it a little easier to comprehend how the coding system could be used to represent text and other characters within computers. It just might spawn a new hobby or jumpstart a young coder’s imagination. more Their Story
