Mazaika is a mosaic creation application. It produces images composed from many small images (aka photomosaic), like a "Truman show" movie poster - a composite of hundreds of little pictures to mimic another larger image. To make good mosaic pictures you must have a collection of more that 1000 different pictures (it's easy if you have digital camera). You can use image files in almost any format for this composition. There are many adjustable parameters to control the creation process. You can save the resulting mosaic picture as one big image file.
