PolskiFalling Dominoes Spiral (2D)
Top-down 2D chain-reaction lab: an expanding spiral of dominoes topples outward from the center. Adjust fall speed, topple angle and reset pause and watch each domino's ground footprint grow as it tips into the next.
This 2D companion renders the same spiral of 150 dominoes as the 3D version from directly above: each domino is drawn as a rotated rectangle whose footprint lengthens as it tips, so the chain reaction reads as a wave of growing shapes spreading outward from the center rather than a 3D toppling animation. The fall-speed, topple-angle and reset-pause sliders drive the identical staggered-start timing model as the original, letting you compare how those parameters change the wave's shape without needing to orbit a camera.
Top-down Canvas2D chain-reaction lab: a logarithmic spiral of 150 dominoes topples outward from the center with staggered start delays and an eased fall curve, matching the timing model of the 3D version.
