This week, Gravilux for Windows 8 showed up free in the marketplace (but it will only be of no-cost for a limited time). The app is an “interactive musical star field visualizer”; simply touch the screen and simulated stars are whirled around and began to change color. You can even set the stars to react to music or other audio files in a custom playlist

Gravilux is a fun tool to amuse your friends with and show them what your fancy Windows 8/RT touch screen can do.

Download the app here.

Let us know what you think. Gravilux is also Microsoft’s Windows 8 App of the week.
