A real 3D duck, floating on an invisible skin of water drawn right on your screen. No window. Quietly alive. Yours for $2.99.
What it is
Drag it around, flick it across the screen, squeeze it until it squeaks. Leave it alone and it breathes, drifts, watches your cursor — then comes to a complete, water-flat stop. Doing nothing has never looked so good.
Under the surface
A wave-equation heightfield ripples out from every bob, drift, and splashdown. Calm water draws literally zero pixels, then fades back to nothing.
Turn on Screen water and the duck’s wake bends your actual windows and text through a refraction shader — your desktop, underwater.
A squeezy bubble-bath bottle, a fishing rod that only ever catches bath toys, a slice of real bread the duck paddles over to eat, minnows, koi, and ducklings that follow in a line.
Chunky dithered pixel-art, cel-shaded, smooth lit 3D, or liquid chrome — swap the whole style from a right-click ring of iridescent bubbles.
The window is transparent and click-through everywhere except right on the duck. It sits on top of your work without ever getting in the way.
Hand the duck a little picket sign — “back at 3” — and it holds it up. Throw the duck and the sign leans back into the airstream. Because why not.
How to play
Get the duck
One purchase covers both macOS and Windows — buy once, put the duck on every computer you own. No subscription, no account to make.
A signed .dmg for Mac and a signed installer for Windows, delivered the moment you buy.
One-time payment · instant download · see it first
macOS 11 Big Sur or later (Apple Silicon & Intel) · Windows 10 & 11, 64-bit. Every future update, free. A license key that unlocks the duck on your machines.
A note on the first launch. The Mac build is signed & notarized by Apple and the Windows installer is code-signed, so both open straight from a double-click — no scary “unknown developer” warnings. The Screen-water mode needs Screen Recording permission — the duck asks on first use, and captures never leave your machine.
