SplashDuo
Native for macOS

Your desktop.
In motion.

SplashDuo makes your desktop appear to stay upright as your MacBook closes—an uncanny, fluid illusion rendered live on your Mac.

Made for motion.

01

Tracks the hinge

On compatible MacBooks, SplashDuo reads the lid angle live. Manual control keeps the full experience available on other Macs.

02

Reprojects every pixel

A physically based perspective model keeps the bottom hinge anchored while the desktop bends and stretches into place.

03

Renders on the GPU

Metal redraws the effect in real time for a smooth, responsive illusion that feels native to the hardware.

Make it yours.

Choose razor-sharp clarity, deep directional shade or a luminous crystal edge—then tune the perspective, stretch, blur and shadow until the motion feels right.

On-device processing

Your screen stays
on your screen.

SplashDuo processes display frames live in memory. Nothing is recorded, stored or uploaded—because a visual effect never needs to become a data trail.
