Computer and art mix very nicely. We can algorithmically generate patterns, be it pictures or music, which are aesthetic.
Here is an example program for *nix systems which generates fractal like tiling.
We use tga format, which is simple but uncompressed. For compression, we may use imagemagick suit's convert command.

The same program can be written in python too, easier to write, but slower in execution
