High Adventure Games gives us a link to Terraonova: The Planet of the Day. You may recognize the author of that program. It’s John Walker, the founder of Autodesk, Inc. and co-author of AutoCAD.
The cool thing is that he’s given me permission to use the script that powers that feature as part of my project, Colonies and Empires. Maybe I’ll work on it someday.
As an aside, I would this as well. Might help me with my work with C&E.
