ISS tracking theme clock face – Monochron Clock Kit. SPACECHRON, Scott writes -

Some of my christmas money went towards purchasing a Monochron Clock kit from Adafruit.com.

It turned out to be an awesome build and I had lots of fun putting it together. I also chose it because it allows you to program your own clock “faces” for it. I’ve programmed a Space themed face for it that simulates the space station ground track. I’ve also programmed an autodim feature for the backlight because my preferred daylight brightness was too bright at night. The fact that I can customize it to fit my needs is an awesome thing. I wish there were more products like it.

Amazing, and the code is GitHub.
