"name": "Recording. Shows a slider controlling the overlap of two blurred pixelated particles. The slider brings them closer and closer until some of their semitransparent edge pixels overlap and the overall assembly alpha increases there. On hovering each pixel, the assembly alpha there is shown in a tooltip. On the right, it's also shown if there is non-transparent pixel overlap there and also how the assembly alpha was computed in that case.",
