Code Rain

A rain of green characters as your screensaver, smooth and offline.

Code Rain lets columns of green characters fall over a black screen — mirrored katakana, digits and symbols — like in the science-fiction films of the 1990s.

• Android screensaver: Settings → Display → Screen saver → Code Rain; it starts while charging or docked
• Also a full-screen app that keeps the screen on
• Pinch to make the characters larger or smaller
• Smooth, even on small tablets and older phones
• A long press opens About (licences, an optional tip)
