Author Comments:

Uses some simple routines to randomly generate a selection of planet textures to give quick, on-the-fly visuals. Very messy code (sorry, if I get the chance soon, Il clean it up) - its just lifted straight from where I was toying with it. Anyway, it should be easy to implement into a custom function.
