Scott's Binary Clock is a clock that displays the current time in binary using a LED display.

It really doesn't serve much of a practical purpose, unless your goal is to display the time in a format that nobody but you can read.

Emphasis has been placed on making the clock cool looking and realistic (the LEDs in the clock were obtained from taking pictures of real-world LEDs).

There are also several different backgrounds including flat black, brushed aluminum, and mahogany.

There is even a new "transparent" background that many people have been asking for!

You can toggle the LEDs between round, square, and rectangular and you can select several different LED colors -- red, blue, amber, green, etc.
