A truly live wallpaper: glowing koi, jellyfish, mantas and other creatures drawn from tens of thousands of points, each one computed from a few trigonometric formulas. Nothing is pre-rendered; every frame is calculated on the fly, so the creatures swim, breathe and twist without ever repeating exactly.

The creatures were inspired by the parametric "tweet-size" generative art of digital artist @yuruyurau.

No special permissions are required. No ads, no tracking, no network access.

Features

• Ten creature styles: Koi, Jellyfish, Manta, Coral, Helix, Breathe, Bloom, Trance, Koi II and Nebula

• Adjustable number of creatures, speed, point count, point size, opacity and zoom


• Shape frequency and amplitude to morph the creatures


• Single color, palette or slowly cycling colors; free choice of background and point color


• Energy saver: pauses after 10 seconds without touch, tap the screen to resume


• Live preview behind the settings

Setting the wallpaper
Open the app and tap Set Wallpaper, then Set wallpaper in the system preview and choose home screen, lock screen or both. You can also long-press an empty spot on the homescreen and choose Wallpapers → Live wallpapers; some devices do this through the Android Settings app instead.
