Interactive 3D Simulation

Real-time physical simulation of a chaotic two-link pendulum rendered in beautiful, high-fidelity 3D space.

Customizable Link Dimensions

Fine-tune the length, hinge offset, center of mass, and pivot points of both links to witness various chaotic movements.

Dynamic Color Selection

Personalize the appearance of each link with an interactive and responsive color picker.

Immediate State Controls

Pause, play, reset, or shuffle physical properties instantly to control the chaotic pendulum behavior in real-time.

Premium KMP Architecture

Powered by Google's Filament rendering engine and Kotlin Multiplatform for buttery-smooth 60 FPS across Web and mobile.

Educational & Fun

Perfect for students, engineers, and scientists wanting to explore multi-body system dynamics and chaotic mechanics.
