Coloring bitmap mosaic plexus
I saw on the website of the public domain an interesting intertwining circles from which to get a round mosaic inflorescence. And the kids liked it! And I think you would be interested to play in the cells of the mosaic plexus. Or apply it as a logo, decoration, background.
Coloring in a raster (pixel) format. If you use a graphics editor such as adobe Photoshop, then using the fill can easily paint a picture. Outlines for coloring perfect to spend some time coloring on the computer. For children this can be fun and not an obsessive study of the work in the graphic editors, and knowledge of the world in different shades and colors.
Coloring can be printed, and then paint.
