Google is putting some of the most Google-y Android apps in the spotlight, and is sharing their source code to spur development of other apps.
The site Android Experiments is showcasing Android apps that perform novel and unusual functions. A compass app, called Landmarker, for instance, puts a spin on navigational tools by letting users explore nearby landmarks by rotating their Android device around them.
Another, called IOIO Plotter, is an Android tablet app that converts photos from the tablet's camera into abstract drawings using physical markers suspended from strings.
There are also apps for smartwatches running Google's Android Wear software. An app called Coubertin Rings displays animated graphics on the watch face to motivate daily physical activity. It uses built-in sensors on the watch to display rings that represent the wearer's daily step count.
