The cursor paints a second photograph over the first, and the trail dries out behind it.
About this tool
Two pixel-registered frames of the same subject share one stage. The pointer stamps the second image onto a canvas through a soft radial brush, so the edge reads as wet paint rather than a hard mask, and the trail erases itself a little every frame until the scene settles back to the original. Brush radius, softness, flow, dry rate, release and hold are all live, and either photograph can be swapped for your own pair. Export a self-contained HTML file when it looks right.
