Pattaizer is an interesting tool which transforms digital images into mosaics or abstract computer art.

The program 20+ algorithms to explore. Some are simple mosaics, perhaps replacing blocks of pixels with spheres, hexagons or lego bricks. Others preserve more detail, including a "Broken Glass" option which displays the image through scattered glass tiles. And a few are almost entirely abstract, replacing the source image with a range of geometric patterns.

Basic operations are straightforward: select an algorithm, click "Update mosaic" and view the results.

Every algorithm may be customised with a range of options and settings.

The finished results can be saved as JPGs, BMPs or PNGs.
