Two Links Double Pendulum vs DeskBalls

Two Links brings one of physics' most beautiful chaotic systems to life. Watch a double pendulum swing, twist, and spiral in real-time 3D — then place it on your floor in Augmented Reality and walk around it. Features • Real-time double pendulum physics (RK4 integration) • AR mode — anchor the pendulum on any flat surface • Orbit the 3D scene freely or let it run hands-free • Adjust link length, pivot position, density, and color • Particle trail from the second link tip • Night sky environment with the Moon and Earth • Pause, shuffle, and watch the chaos reset

Transform your screen into a hypnotic work of art. Newton's Cradle 3D brings the timeless desk toy to life with breathtaking realism and endless customization. Watch seven perfectly balanced spheres swing in mesmerizing motion powered by finely-tuned physics that can run for up to 50 minutes before transitioning to a stunning ripple rain interlude. 11 UNIQUE PENDULUM STYLES Choose from an incredible range of visual aesthetics, each with its own personality: Stone - Natural textures and earthy elegance Fire/Magma - Persistent fire auras with lava-flow textures and explosive 1200-particle collision flames Crystal - Pristine clarity with light-refracting beauty Candy - Sweet, vibrant colors with a playful finish Sports - Classic athletic ball designs Solid Color - Pure minimalism with a built-in color picker for infinite customization Sparkle - 600+ glitter particles with cross-star flares and rainbow washes Liquid - Glass-like transparency with mesmerizing sloshing textures Hologram - Futuristic scan-line scrolling with dynamic glitch effects Ice - Frost shimmer with pulsing crack glow Nebula - Cosmic swirl rotation with evolving color cycles 6 IMMERSIVE ENVIRONMENTS Set the perfect atmosphere for any mood: Air - Complete day-night cycle with natural lighting transitions Underwater - Teal fog, dancing caustics, floating bubbles, and low-pass filtered collision sounds Colorful Sunshine - Bright gradients, fluffy clouds, a radiant sun, rainbow glitter, and grass floor Space - Galaxies, twinkling stars, and distant nebulae Wireframe - Minimalist technical aesthetic Cosmic Flow - The crown jewel: cosmic nebula backgrounds, 600 drifting sparkle particles in 3D, 5 orbiting glow lights, translucent flow planes for depth, no floor, enhanced ball reflections with per-ball colored glow and rim lights, 5 dramatic pulsing spotlights, and 5 sweeping blurred wave light planes RICH AUDIO DESIGN Every collision produces synthesized sounds uniquely tailored to your pendulum style and filtered to match the environment.
