I really like the concept art the KSC visitor's center has come up with.
First, they posted this:
I nitpicked about it... "I think it'd be nice to let visitors get a closeup view of the top of the shuttle, perhaps one where they could at least look at the interior through the windows. Also what if the payload bay doors were open, the radiators and KU band antenna were extended, and some no-longer-needed equipment (Such as an Orbital Docking System, an MPLM, or a Spacehab module) installed inside the payload bay? Even though it can't hold it's own weight by itself on the ground, it'd also be cool if the arm was extended. That would give visitors a better idea of what the shuttle is like while it's actually in orbit."
And 4 months later, I was excited when they posted:
The JSC visitor's center didn't like my advice though </3 "James, Your right, it would be an impressive display. We are very open minded on different ways to display it. Currently, the doors and Canada Arm require a lot of external structure and support in Earth’s gravity. This could make it difficult to view."
