Triple Pendulum Cathedral
Custom Triple PendulumMore Demos
Wrecking Ball
Drag a glowing neon wrecking ball on a chain and demolish towers of stacked boxes. Full rigid body physics with constraints, collisions, and gravity.
Newton's Cradle
Classic Newton's Cradle with neon glow and real elastic collision physics. Pull back any ball and watch momentum transfer in real time. Click to interact.
Cloth Simulation
A cloth mesh that flows in the wind, tears when pulled too hard, and drapes realistically. Grab and drag any part of the cloth. Built with Verlet integration — no physics library.
Gravity Wells
Hundreds of particles orbit gravity wells you place with your mouse. Click to spawn new wells, right-click to remove. Watch orbital mechanics emerge naturally from gravitational math.
Domino Effect
Tap the first domino and watch the chain reaction ripple across the screen. Dominoes knock each other over with real rigid body physics. Click anywhere to reset.
Fluid Splash
Move your mouse to pour fluid that splashes, pools, and flows realistically. Built with Smoothed Particle Hydrodynamics (SPH) — the same technique used in film VFX.
Event Horizon
Feed a ravenous black hole and watch matter bend into a blazing accretion disk. Stars warp around the core while glowing debris spirals into the singularity.
Jelly Reactor
Drag unstable neon blobs, slam them together, and watch them wobble, squash, and pulse like radioactive jelly. Soft-body physics with glowing impact shockwaves.
Chaos Pendulum Field
A synchronized field of double pendulums starts together, then explodes into impossible-looking trails as tiny differences amplify into pure chaos. Tap to reseed the field.
Ferrofluid Lab
Push magnetic points through a glossy ferrofluid field and watch spikes bloom, collapse, and drift under your cursor. Drag to reshape the liquid-metal surface.
Chladni Plate
Excite a neon plate with shifting harmonics and watch sand race into crisp nodal geometry. Tap to cycle modes and reshape the standing-wave pattern.
Bridge Failure
Load a suspension bridge until the deck sags, strain lights up, and joints snap in a cascading collapse. Drop loads to push the structure past its limit.
Binary Star Slingshot
Launch comets through a twin-star system and watch them sling, capture, or escape on bright orbital trails. Click to fire a new probe.
Gravitational Wave Ripple
Trigger a collision pulse and watch spacetime ripples move through a neon star lattice. The whole field bends, flashes, and settles.
Plasmoid Reactor
Confine charged plasma loops inside a magnetic bottle, then overdrive the field to erupt in reconnection bursts and glowing jets.
Sand Avalanche
Pour neon sand into fragile slopes, carve cavities under the pile, and watch the whole face collapse in glowing moving fronts.
Glass Fracture Lab
Drive impacts into a charged glass pane, watch stress lines branch across the surface, then blow it apart into glowing shards.
Marble Machine Catastrophe
A neon marble machine hums through ramps, pegs, and gates until overload floods the tracks and turns precision into pure catastrophe.
Magnetic Pendulum Fractal
Launch a damped pendulum over neon magnets and watch tiny changes in the release path snap into different terminal basins. The trails reveal chaos through destination, not symmetry.
Gyro Precession Lab
Sweep torque across a glowing gyroscope and watch wobble, precession, and spin lock together into something elegant and slightly alien. Boost the rotor to change the whole motion language.
