This app is designed for those who love to watch a colorful screen on their Windows Phone. After activating the app, you will see a black-and-white disc spinning on your screen. In the arcs of the disc, you can see the faint colors, of which the saturations depend on the spinning speed.
Different colors will be produced by different sections of the arcs, and they will vary from reddish to bluish. The orders of the color change will be reversed as the spinning direction is reversed. To stop the spinning, you just need to touch the disc. What an easy and attractive app!
