The project in detail
Sillage is a mechanical labyrinth: eleven three-dimensional marble courses, from La descente to La triple bascule. You hold the phone like a tray, tilt it gently, and the steel ball rolls, bounces and takes on ramps, cambers and bridges with no rim.
The perspective follows the real position of your face: moving the phone or looking from the side lets you see the tracks below. Every track is a solid object, with no magic passage. Numbered markers serve as checkpoints, and progress is saved on the device.
A native Metal and SwiftUI app, in development for iPhone and Mac.
