A holographic fridge magnet app built with SwiftUI. Peel stickers from a tray, slap them on a retro fridge, and watch them shimmer as you tilt your phone.
Each sticker is a stack of 7 layers:
- Shadow silhouette — white outline that casts a dynamic shadow (lifts on drag)
- Sticker artwork — the actual illustration
- Dark outline — subtle depth ring at 15% opacity
- Holographic gradient — a 7-color
LinearGradient(pink → purple), blurred and masked to the sticker shape. The phone's gyroscope feeds pitch/roll data that shifts the gradient position and rotation in real time. That's the shimmer. - Ghost artwork — sticker again at 25% opacity, lets colors bleed through the holo
- Film grain — subtle noise texture for realism
- Glare strip — dark gradient that sweeps on drag, simulating light reflection
No Metal shaders. No third-party libraries. Pure SwiftUI.
- 🧲 Drag stickers from tray onto fridge
- ✨ Gyroscope-driven holographic shimmer
- 🔊 Magnet snap sound on drop, peel sound on pickup
- 📏 Pinch to scale, rotate, drag to reposition
- 🎯 Settle animation — stickers slide down slightly before the magnet catches
- 🔍 Double-tap for 3D inspection mode with layer separation sliders

Holographic sticker wall concept inspired by Daniel Korpai. Rebuilt with a fridge magnet interaction and custom retro space sticker artwork.
