Wow, that link you posted reminded me of some stunt my Astronomy professor from Freshmen year pulled.
Another student asked him to show the Earth and Moon in perspective and he just casually puts two tiny dots on a chalkboard, spaced well apart. So, the girl gives him a confused look, and he says: "What... they're too small, right? Well, would you like a larger illustration?" So, she says yeah. He says to imagine that the CRT monitor was the Earth (he cautions her to pretend that it's roughly spherical - which I found amusing). Then, he takes the tennis ball off his desk and starts bouncing it. Having some inkling as to what he would do, I expected him to chuck it at the back of the room (he'd done similar things before), but he just says, "Hold on" and leaves the room. He doesn't return for the remaining ten minutes of the class. As was the custom, we all left right on time, and we find him at the end of the corridor (there was only one exit from the underground rooms) smiling as he eats an Express Lunch hotdog in one hand and bounces the tennis ball the other.

As for the game, I just wonder why they opted to use magenta and green stars instead of standard spectral class colors. This is different from the size considerations since there would be no harm in having red-orange, orange-yellow, yellow-white, white, white-blue, and blue stars instead. All a Galciv modder would have to do is change the green stars to white and the magenta ones to blue...
