Product Description:
MacOSaiX lets you create a mosaic representation of an image from hundreds or thousands of individual images. The individual images can be found on local disks, created randomly from fonts, found by keyword through Google's or flickr's image database, pulled from iPhoto or pulled from QuickTime movies. You can also choose rectangles, hexagons or puzzle pieces as the shapes of the tiles in the mosaic. MacOSaiX will automatically determine the best location in the mosaic for each image.
