Geek Clock
Geek Clock is an app that I originally developed for the iPhone / iPod Touch and decided to bring it to the Mac.

Geek Clock is a binary clock that displays the current time ( hours, minutes and seconds ) in binary on or off fashion. A light that is on represents a binary 1, whereas a light that is off represents a binary 0. This is a must have clock for all the geeks out there.
