Double Helix is a live wallpaper and daydream that features an immersive 3D scene with a stylized version of DNA molecules. Swiping the screen shifts the viewpoint and subtly stirs the particles. It is built on the libGDX game framework, and uses several custom OpenGL ES shaders to produce the translucent glass material, blurred background, chromatic aberration, and particle depth-of-field transitions. If you like it, check out the premium version. It has options for setting the scene color (can be linked to battery level) and film-grain, scan-line, and vignette effects.
