ColorMixer is a free personalization application for Android developed by Marcin Wojciechowski. It is a real-time OpenGL animation that features twelve different color modes and allows users to adjust GPU and battery usage with three different resolutions. The application also offers five complexity levels to adjust animation details, FPS limitation, six different speed settings, and high speed and optimization.

The application is easy to use. Users can set it up as their live wallpaper by selecting "Wallpaper" from the "Menu" or long-holding on their home screen and then choosing "Live Wallpapers." From there, they can select "Color Mixer Live Wallpaper." The animation's true 'magic' lies in the math behind it, specifically differential equations.

Overall, ColorMixer is a great personalization application for Android users who enjoy real-time OpenGL animations. It offers a variety of customization options and is easy to use. In case of any issues, users can contact the developer via mail or Facebook.
