[ajcstplo] Chess problem exhibit

Create a museum exhibit of chess problems.  This should be fairly easy as there already exist many collections of beautiful chess problems.  Some curation challenges still exist of choosing which ones, and organizing them into a physical space: perhaps by theme, perhaps in order of difficulty?

Large board diagrams so the problems can be seen from anywhere in the room, many physical boards available so people can try solving them, FEN available encoded as a QR code so people can examine them on their mobile devices.

More ambitiously, art can accompany a board diagram which illustrates the theme of a problem.
