Here are a few samples of the output generated by a couple of the imaging functions that will be included in Magrathea.
The first image is an early output from the "Venus Class" planet generator. Final versions will not be in blank and white but will support a color palette.
The second image was generated using the "Image Map" generator (using an image map of Saturn) with ring generation turned on.
This third image is just something I threw together while debugging.
