The Ultimate Geek Clock. This clock displays the time in binary. There's no better way to geek up your iPhone.
A Geek Clock features 5 different LED colors to choose from as well as choosing between a 12 and 24 hour format. The clock also contains a Learning Mode that you can turn on and off. Use it to learn how to read a binary clock.
Last but not least you can set the clock to override your auto lock settings so that you can set it up on your night stand and fall asleep to mesmerizing lights, it also works well as a flash light.
The settings for A Geek Clock can be found in the main settings app on the iPhone under A Geek Clock.
Note: iOS 4.0 and newer supports a 24-Hour time format which if turned on makes A Geek Clock crash on startup. I will be submitting an update soon that fixes this. For now you can go to Settings -> General -> Date & Time and turn of 24-Hour Time and the app should work fine.
