The Secret History of Spelljammer and a Question

Former TSR game wizard Jeff Grubb has done a another "secret history of" post on his blog, this time about Spelljammer--a game near and dear to his heart--that I think is fascinating. There's a lot to love/learn from his post, but some of the best is the fact that the game was inspired by a single image:

One of the things that I came into the pitch session with was the idea that I wanted to push the envelope on what D&D fantasy was. Yeah, we had done FR and DL, but those had been written down as typical fantasy worlds. Vanilla fantasy. Default fantasy. Background static. Here was a chance to go out on more of a limb and push the envelope. So this was the chance to do D&D in space. I’m sorry – Innnnn Spaaaaaaace!

He goes on to describe that image:

A knight standing on the deck of a ship in space. He doesn’t freeze. He doesn’t blow up. He doesn’t float away. Everything that follows comes out of that one image, which is captured (with more to it as well) on the final cover Jeff Easley did. All what people have called “Grubbian Physics” with its air envelopes and its gravity planes, comes from creating a universe where that image is true.

If that's not the definition of weird science fantasy, I don't know what is. Sure it seems wacky at first, but it led to a whole new way of thinking in the game and opened a really imaginative approach to the genre (which he talks more about in his post).

Fair disclosure: I'm not even a fan of Spelljammer. Always thought it was a little too out there, which is my own fault for not giving it a chance. But I'm willing to admit what a fool I've been! Anyway, I'm just getting to the good part, which is:

For the boxed sets at that time, we had a format – two 96-page books, 4 big color maps, and a bunch of light cardboard sheets. Our task was to fill that space. Sometimes the format worked, sometimes it was less successful. For Spelljammer, we used them to create the ship stat cards and standups. So that worked out pretty well.

A Challenge!
So, here you have a template:

• 1 box, 
• 2 books
• 4 maps
• Some cardboard sheets

Make a game. Take an image--real or imagined--and base an entire game on it. Think what the cover would look like, what the books would cover, and most intriguingly, what do you do with those cardboard sheets?

Using the same items and format, what type of game do you come up with? To the comments my friends!
