Metapixel is a photomosaic generator. It can generate classical photomosaics, in which the source image is viewed as a matrix of equally sized rectangles for each of which a matching image is substituted, as well as collage-style photomosaics, where the images are placed at arbitrary positions in the source image, not aligned to a matrix.
