Stop holding your Nexus 7 in your hands like a chump and check this out. These industrious modders have built and installed complete Nexus 7 mounting systems in a Subaru STi and Toyota Celica. The Toyota owner even created a launcher skin to go with the mod. The skin, of course, is based on Knight Rider (seen below).
The modder with the Toyota used Nova Launcher, UCCW, and Simple Text to build a simple Knight Rider UI that gives access to the most commonly used functions.
I recently took up bike riding as a good way to get outside and get active. Being a tech-junkie and overall stat-lover, though, I immediately wanted a good way to track my rides in detail, including real-time MPH, distance traveled, and all the other info that may help me better keep up with my progress. Instead of going the traditional "bike computer" route, though, I decided to use my smartphone to accomplish the task at hand.
