- Photo Album Screensaver A fullscreen digital photo frame: it opens straight into a slideshow of curated high-resolution landscape and art photography with slow Ken Burns pan-and-zoom and smooth crossfades. Pick a local folder to shuffle your own pictures — files are decoded in the browser and never uploaded.
- Aquarium Simulator A calm 3D virtual fish tank you can simply leave running: schools of blue tetras cruise past, tangs, butterflyfish and clownfish weave between them, a long-finned betta drifts by and a big fish patrols the sand. Seaweed sways, bubbles rise, light beams and caustics ripple across the floor, and rocks, pebbles and scattered scallop and conch shells rest on the sand. Move your pointer and curious fish swim over; tap once to scatter a pinch of food and watch them dart in. You get 6 pinches of food a day — and once they are gone, tapping the water still sends out ripples that draw the fish over. The more they eat the bigger they grow, from tiny fry to full-grown fish — and even if you do not feed them for days, they still grow a little on their own every day. Nothing starves, nothing dies, progress only goes up and is saved on your device. No score, no failing, no end — perfect as a screensaver or background.Every few minutes a gentle current drifts through the tank: the fish, the seaweed, the bubbles and the light all shift with it, so nothing on screen ever stays frozen in one spot.
- Aurora Screensaver A window onto the polar night, floating high above the polar sky — no ground, no horizon, sky from edge to edge. The aurora is not a texture or a flat color band: every frame is raymarched through the upper atmosphere, so the curtains have real depth, folds and S-shaped curls, and stack in front of and behind one another. The colors follow the real emission lines by altitude — the 557.7 nm oxygen green dominates from roughly 100 to 200 km, a crimson 630 nm glow feathers away above 200 km, and during a breakup the lower edge picks up nitrogen violet and a magenta fringe, always cut off by a knife-sharp lower border. The night runs a real substorm cycle: a quiet green arc hangs for minutes, then the whole curtain flares and curls, surges poleward and splits into several bands, and finally decays into patchy pulsating aurora breathing on its own rhythm. Durations and strengths are sampled at random, so no two nights repeat. Behind it, stars are sampled at real spectral-type abundances and colored by blackbody temperature, dimming as the aurora brightens. The shapes keep reinventing themselves too: each curtain’s fold amplitudes, travelling-wave speed, thickness and azimuthal spread drift to fresh random targets on their own schedule, always eased so you can see it changing but never catch a jump. Adjust activity level, curtain count, brightness, star density and how fast the shapes morph; tap anywhere for a whole new set of shapes and an instant breakup.
- Black Screensaver A completely black fullscreen page — no buttons, no text, no animation. Great for saving OLED battery, dimming your screen, checking for dead pixels, or as a clean backdrop. It opens straight to black, no setup needed.
-
Busy Ants
A calm ant-colony screensaver you can leave running: ants wander a sunlit lawn foraging on their own — long-press to drop sugar and lead them, swipe to scatter a cluster, or drag leaves, twigs and rocks to block their path. There is no finish line — they duck into either anthill for a rest, then wander back out to keep living. Sugar piles, scattered grain, puddles and the occasional light rain shower are just part of the scenery. The more food they bring home, the bigger the colony grows, from a handful of ants to a bustling nest. No score, no failure, no end — perfect as a screensaver.
- Clock Screensaver A bouncing digital clock that fills your screen, showing the live time and date. Switch between 12/24-hour format, toggle seconds, resize the text and pick any color you like — great for keeping an eye on the time while preventing screen burn-in.
-
Coding Terminal
A full-screen fake developer terminal that never stops working. Commands are typed out character by character, then build logs, test runs, real source code and kernel boot messages scroll up the screen, exactly like someone coding late at night. Commands come in realistic workflows — edit, commit, push; inspect a container, read its logs, restart the service — so dozens of everyday Linux, macOS and Windows commands go by and you might even pick a few up. Switch between Linux, Windows CMD, PowerShell, macOS and Hacker styles, and tap anywhere to fire off another command.
- Cosmos Screensaver An endless window onto deep space. The camera cruises forward forever along a smooth, randomly drifting course while the Milky Way band, stars, clusters, wispy colored nebulae and faraway spiral galaxies stream past. The galaxy is computed from a real disc model: the bulge toward the galactic centre, the dust rift splitting the plane, the fade toward the anticentre, stars clustering onto the plane, all drifting with the Galaxy’s differential rotation. Star colors are not hand-picked: spectral types are sampled at their real abundances, then converted from blackbody temperature, so you get everything from dim red dwarfs to hot blue-white giants, dimming and shrinking with distance. Adjust cruise speed, star density, nebula density, how often the course changes and how much the view drifts; tap anywhere to pick a new heading and surge briefly. No score, no end, and no frame ever repeats.
-
DVD Screensaver
The classic bouncing DVD logo, reborn in your browser. The real DVD VIDEO logo drifts across a pure black screen and switches color every time it hits an edge — tap anywhere to send it off in a new direction. Adjustable speed, size, and color theme.
- Emoji Screensaver A fresh random set of emoji every time you open it, floating across a fullscreen canvas and bouncing off each other with real ball-like physics. Choose from built-in Faces, Animals, Scenery, or Plants groups, tune the count, or turn on spinning — the coziest, cutest screensaver around.
- Geometric Screensaver Randomly generated circles, rings, squares, polygons, and stars drift across a fullscreen canvas and collide with true elastic physics — big shapes knock small ones flying. Switch between candy, ocean, sunset, and minimal themes, adjust the shape count, and toggle spin.
-
Matrix Code Rain
The green digital rain from The Matrix, running full screen in your browser. Columns of half-width katakana and digits fall through pure black, glyphs flicker and mutate as they drop, the leading character glows white and the tail fades away. Speed, glyph size, trail, color, and character set are all adjustable, and a tap sends a shockwave through the rain.
- Photo Screensaver Upload a favorite photo and watch it bounce around the screen like a classic DVD screensaver. Drag, paste, or click to upload, resize it however you like — perfect for showing off a pet, family photo, or logo.
- 3D Pipes Screensaver A faithful remake of the classic Windows 3D Pipes screensaver. Colorful pipes grow along a 3D grid in black space, turning at random right angles and weaving around each other, then fade out and start over. Adjust speed, pipe count, and color theme.
- Rhythm Screensaver Grant microphone access and watch five effects pulse to the sound around you — particle bursts, spectrum rings, waveform, polar petals, and a 3D pulsing sphere — with four color themes, a screen that never sleeps, and colors and framing that drift slowly over minutes so nothing burns in.
- Snake Screensaver A cute emoji snake hunts down emoji treats that pop up across the fullscreen canvas — each one it eats joins the head while the last emoji drops off the tail. Adjust its speed and emoji theme for a nostalgic, playful ambient screensaver that starts the moment you open it.
- Text Scroll Screensaver Type any text and watch it bounce around the screen like a classic DVD screensaver, complete with rainbow gradients or bold color themes and adjustable font size — great for a message board or welcome sign.
