Background video that never repeats.

Marbles scatter through a peg field and stack into a bell curve, then the floor drops and it refills.

Balls ricochet through a brick field, clearing it brick by brick before a new pattern goes up.

Coloured sand pours into drifting banks, then the floor opens and the whole pile drains away.

Balls ricochet outward from the centre, shattering every ring segment they touch as the camera pulls back.

Objects are lowered into a blade and fall away a disc at a time, each one a different width.

A jet strips grime off a shirt, a plate, a car, uncovering the colour underneath.

Rocks, papers and scissors roam the arena and convert whatever they beat, until one side owns the screen.

Each deck shutter is solid to every colour but its own, so marbles fall into matching bins.

One ball becomes two on every wall hit, filling the arena before it bursts and starts over.

Two colours trade ground tile by tile, each runner flipping enemy territory as it bounces through it.

Orbs drop into a jar and two of a kind fuse into the next size up, chaining until it overflows.

Tuned pendulums drift out of phase into travelling waves, then snap back into one line.

A shuffled spectrum sorted bar by bar, resolving into a clean rainbow before it reshuffles.

Blocks place themselves into the flattest fit, clearing rows in a run that keeps itself alive.

Balls swell with every wall they touch until the arena cannot hold them and it all resets.

Marbles spiral inward down a whirlpool, vanish into the drain, and return to the rim.

A platen bears down on a blob until it gives, scattering it across the floor.

A mower works across an overgrown field, steering around trees and leaving banded stripes.

Marbles race down a course built as they fall, and the first one past the flag wins.

A ball bounces inside a turning ring, waits for the opening to come round, and breaks out into the next one.

Rows of dominoes on stepped shelves go over one row at a time, sweeping back and forth down the board.

A bed of pins that objects press through, one silhouette resolving after another.

A maze is carved, a search floods it from one corner, and the only route out lights up through everything it tried.

Double pendulums released a hair apart swing as one, then split into chaos, each colour tracing its own path.

Shells climb over a city at night and burst into peonies, rings, willows and hearts, building to a finale.

Two spiral galaxies fall together, tear tidal tails out of each other on the way past, and merge.

Hundreds of starlings turn as one at dusk, and a falcon dives through them in a rippling black wave.
