MOSAnICk is a utility that creates mosaic-based pictures. Essentially the pictures that MOSAnICk creates are based upon a source image (which, obviously, supplies information on which parts of the result should be red, which parts should be dark, etc.), but is itself made up from dozens / hundreds / thousands of miniature pictures.
MOSAnICk keeps multiple image databases (generated by you) of pictures. The pictures are stored in either Portrait (upright) or Landscape (sideways) format, depending on the dimensions of the source images you supply. When generating a mosaic, source images of one type are loaded from a database and made to fit a scaled version of a target picture using various adjusting techniques. These adjusting techniques include various image lighting and tinting models, as well as image mirroring.
