I recently saw an app that lets you make art using numbers. The mechanics were simple but the shapes were quite complex. So, I thought, why not make a simple app made out of squares and randomly generated numbers to create the most random kind of art on your device.
This led to Colornums and this is the one app that you need to color your mood. A random palette of numbers is generated each time you open the app and you simply need to replace the numbers with colors.
As such, the art is unique each time and you get to have plenty of fun making the drawings in the simplest manner possible.
Colornums is currently available on Google Play and Samsung Galaxy. Download links below.
