Light & Shadow Lab: Prism Sim

A light and shadow simulator with real color mixing and a working prism.

Turn your phone into a hands-on optics bench. Light & Shadow Lab is a light and shadow simulator where every shadow, reflection, and color effect is calculated live in real time — not a pre-rendered animation. Think of it as a pocket optics simulator you can play with for hours.

Drag colored lamps around a dark room, drop in shapes, and watch physics-based shadows, color mixing, and reflections happen instantly, the same way they would with real light.

✨ WHY YOU'LL LOVE IT

💡 Real Light & Shadow Physics
As a true shadow simulator and light physics simulator, every shadow is calculated live from each light's exact position and angle — move the light and the shadow moves with it, instantly.

🌈 A Real Working Prism
This isn't decoration — it's a genuine prism simulator. Shine light through a glass prism and watch it disperse into a real rainbow spectrum, with the spread changing based on the light's own color.

🔴🟢🔵 RGB Color Mixing
Part color mixing app, part RGB light mixer: overlap red, green, and blue light to create yellow, cyan, magenta, and white in real time. A simple, visual way to understand how colored light actually mixes.

✨ Reflective Surfaces
Add glossy shapes that catch and bounce light back with realistic highlights and glow.

🔷 7 Interactive Shapes
Squares, circles, triangles, pentagons, hexagons, crosses, and stars — combine them however you like, almost like a shape and light game.

🎛️ Full Creative Control
Move, recolor, resize, or delete any light or shape with a simple tap or drag. No limits, no locked tools.

🌙 Relax Mode
Sit back and watch a slowly shifting, ambient light show — a relaxing sandbox app for unwinding, no goals or pressure involved.

🌍 3 Languages, Full RTL Support
Available in English, Español, and العربية, with complete right-to-left layout support.
