I decided to play with mrxak's planet generator, and made a full set of replacement planet and moon graphics for the EVC port for Nova, and by extension, several TCs built from it. Please enjoy.
I may have future updates, perhaps for other EVC-based TCs or plugins, or EVO.

Special thanks to mrxak for the planet generator tool, and Guy for the graphical system editor in ResForge (as of the time of this post, in pre-release testing).
