Setup
Target image
or drop / paste one here
The window is cut from the image: its outline becomes the silhouette, and every piece takes its colour from the glass it covers. Transparent PNGs cut cleanest.
More pieces resolve finer detail; fewer make each donation count for more on screen. Detail shrinks pieces around the busy parts of the image and enlarges them across flat areas.
How many colours of glass the window is cut from. High counts follow the image closely; drop it for a bolder, more stylised window that reads as a limited rack of antique sheets.
Re-cuts the same design a different way. With no image loaded it generates a gothic lancet from scratch.
