Recently i programmed a mobile applications with LWJGL (java) and this video shows the result. A sunsystem with circular rotating planets with different velocity. The planets also have a horizontally rotating texture (made of a quader) and a half-circled shadow with the correct angle away from the sun.

This is just a showcase of the animation and not the programm itself - maybe i post it in another video if you like. Also tell me what you think about the animation. Anything to improve before i turn it into a game on the appstores?^^
