Game of Life Mosaics
Turn a portrait into a mosaic of Conway's Game of Life still lifes. Upload any photo. If it still has a background it's removed automatically, but a toggle lets you keep the original if you prefer.
Note: the first upload takes a while as the background-removal model loads in the background; later uploads are quick. You can skip this by uploading an image whose background is already removed (e.g. via remove.bg).
