Seed points are scattered on a Poisson-jittered grid (~36 in Normal, ~64 in Vivid); each pixel on a small off-canvas buffer is assigned to its nearest seed, forming Voronoi cells. The buffer is rendered with nearest-neighbour scaling to fill the canvas, and true cell-edge gridlines are stroked in black on top to produce the lead-line effect. Per-cell brightness lerps toward a target that's higher when the cell is near the user's motion centroid, so moving "shines a lantern" across the glass.
