Mazaika is a photo mosaic tool. It can create pictures made of other pictures. How Mazaika works: Every region of the source image is replaced with some image from a collection, that most closely resembles the original image. When searching for an appropriate image Mazaika considers not only the overall color of the source image part but also takes into account the inner color and the brightness distribution within. The more pictures in your collection - the more accurate the match. The more different colors and brightnesses in the pictures in the collection - the more accurate the match. In the gallery section you can see some source pictures rendered with different collections.

It appears that not every image can be rendered with every collection. Good results can be reached even with collections of under 1000 pictures.  Obviously the more cells (tiles) in source the picture - the more detailed the mosaic will be. 1000 - 2000 tiles is usually enough. Mazaika can consider small parts of the tile pictures to make up detailed parts of the larger picture. This means that two or more tiles may work together to correctly represent a section of the big picture. Mazaika is the only photo mosaic program that allows you manualy change single tiles if you don't like them.
