About This Software

Lumi moves in

Little Lumi Model puts Lumi on your screen and lets her live there. She walks along the bottom of your monitor, climbs the side of the window you are typing in, hangs from your title bars, and sits down for a nap when nothing is happening. She is not an app you open and close. She is simply there, doing her own thing, while you work.

What she does

• Walks, runs, sprints, skids. Full-speed dashes that stop with a puff of dust.

• Treats your desktop as terrain. Walls, ceilings, window edges, window faces — and she will dive off a title bar for no reason at all.

• Never quite idle. Head tilts, humming with floating notes, little hops, sitting down and looking around.

• Reacts to you. Pick her up, shake her, throw her across the screen. Click once and she says hello.

• Takes requests. Right-click for a specific action, or call her to your cursor from the tray icon.

• Comes in numbers. Summon as many Lumis as your desktop can hold.

74 behaviours run on 92 frames, every one of them drawn by hand. Thirteen of them can be requested directly from the right-click menu.

Built to be left alone

• Nothing to install. The Java runtime ships inside. No separate download, no account, no internet connection.

• Quiet by default. No launcher, no login, no notifications, no background service.

• You choose her playground. Pick which applications she is allowed to climb.
