Bird Museum

You have an entire empty museum at your disposal, display cases and everything ready (as well as some staff to make proper stands and whatnot).

You're a bird though.

You can go fly into the archives and pick up artifacts to put on display, opening halls as you fill them.

You can also go out into the city and scavenge/steal any random junk and lug that back to the museum. It can still be a masterpiece if it smells a bit.

Go show the world what you think is interesting!
