Particles & Physics

20 components, each a single self-contained HTML file — no frameworks, no build step. Preview them here, or see them live on the canvas.

• Gravity Dot RainMulticolored dots fall under gravity with motion trails, bounce off the floor, and scatter away from the cursor on a dark navy canvas.
• Firework BurstColorful glowing sparks burst radially, fall under gravity, and fade against a dark sky. Auto-launches bursts; click anywhere to add more.
• Confetti CannonColored rectangles fire from bottom corners in auto-cycling bursts, tumbling with gravity and flip animation. Click anywhere to trigger a cursor burst.
• Bouncing Balls7–14 glossy pastel balls bounce off walls and collide with elastic physics; cursor repels balls within a 70px radius.
• Spring ChainA 16-node spring chain whips and follows the cursor in a lime-to-gold gradient; drifts in a figure-eight pattern when idle.
• Cloth Wave GridAn 11x11 wireframe grid ripples like cloth via sine/cosine waves in cyan-to-violet hues; mesh nodes bulge away from the cursor on hover.
• Metaball Fluid7 hot-pink blobs drift and merge via a high-contrast canvas threshold; cursor adds an attracting blob that pulls them toward the pointer.
• Boids FlockingUp to 60 lime-green triangular boids flock using alignment, cohesion, and separation rules; they flee the cursor on a dark canvas with motion-trail fade.
• Pointer TrailRainbow spark particles arc off the cursor position, fading with a glow trail on near-black. Auto-orbits in a Lissajous path when the pointer leaves.
• Iron Filings FieldA grid of short rods aligns to a roaming dipole magnetic field like iron filings; rods tint red/gold by nearest pole and react to pointer.
• Sandfall HourglassAmber sand grains fall through a cellular-automaton hourglass cavity, piling realistically at the base; auto-flips when drained, click reverses gravity.
• Double Pendulum GhostA double pendulum swings chaotically in emerald, tracing a slowly fading color-shifting ribbon ghost on canvas; pointer nudges velocity, click rekicks.
• Smoke Vortex Street300 teal smoke streamlines flow past an invisible cylinder, shedding alternating Karman vortices; pointer repels nearby particles revealing the swirling wake.
• N-Body WaltzFive glowing gravitational bodies orbit and sling each other in deep space, trailing colored comet tails; pointer perturbs the dance, click reseeds.
• Liquid Pour SPH200 SPH fluid particles pour into a basin, slosh, and drain on a slow cycle with additive-blend cyan glow; pointer move tilts the fluid sideways.
• Strange Attractor Swarm560 hot-pink particles trace the Aizawa strange attractor in 3D, glowing with additive blend; pointer spins the view and boosts simulation speed.
• Verlet Rope BridgeAmber glowing rope sags between two pegs under invisible rolling weights via Verlet physics; pointer disturbs it, clicks launch new loads.
• Charged Plasma LatticeCharged particles attract/repel via Coulomb forces; teal bonds crystallize between opposite charges as temperature pulses between order and chaos.
• Soft-Body Jelly DropA glossy green jelly blob simulated with 22 Verlet nodes and pressure-volume constraints repeatedly drops, squashes on impact, and bounces back up.
• Pollen Brownian DriftUp to 260 warm and grey motes drift sideways on a cream field with random Brownian jitter, leaving faint fading trails; pointer and click stir gusts.
