Hey, welcome in. This is a little world of drifting particles to sit with, play with and reshuffle. Take your time.

Nothing here can break. Press anything you like.
Shuffle All, the first button in the menu, makes a brand new scene. No two are ever the same.
Move or tap over the particles. They notice you.
Too busy? Slide Chaos down. Want more? Slide it up.
Lost one you liked? The back arrow takes you back through every scene.
Need a breather? The pause button (or Space) stills everything.

Nothing you do here is tracked or sent anywhere. Scenes stay on this device unless you choose to share one.

Fine-tune performance and behavior. These preferences are stored on this device only and never included in share links.

Auto pause hidden tabs

Automatically pause the animation when the tab loses focus or leaves the viewport. Saves battery/CPU when multitasking.

Battery saver mode

Caps particle count, FPS, and heavy FX to keep laptop thermals low while you experiment.

Gentle drift

When you leave it be, the scene slowly evolves by itself, one small change about every minute and a half. The back arrow can always take you back.

Sound (beta)

Soft generated tones that follow the scene: its colours set the key, chaos sets the pace, and tapping the particles plays notes. Starts quiet and fades in. Never uses your microphone.

Tip: turn on the first two when screen sharing or running on battery.
