The Gold edition of Double Helix Live Wallpaper includes the premium settings unlock without any in-app purchase.

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, out-of-focus background, chromatic aberration, and particle depth-of-field transitions.

The scene color can be set to change with the battery level, and there are optional film-grain, scan-line, and vignette effects.
