The Liquib Mosaic Tool was applied to a photo of book shelves in a
book store. Tile Shape was set to Octagonal, Tile Content
to Averaged Colors, Tile Size to 22 and Shape Regularity %
to 22%. The low Shape Regularity % gives the rendering process
flexiblity with adjusting the tile shapes to align with image edges, though the
resulting tiles don't much resemble ideal octagonals.
