Space Monkeys is a conquer-the-galaxy game based on original rules by Stephen W. Glenn, with his permission.
Here is a screen shot of the FLTK version.
Here is a copy of the original rules as designed to be played on a Go board.
Note that this version does not implement any of the "technology chip" rules.
I originally wrote it for Ruby/GTK, then ported it to Ruby/FLTK, and recently created a wxruby version.
It is released as GPL software.
