Looks lovely. Could be used in art galleries for comments & doodles about the exhibits (then unrolled to make an exhibit itself).
I have been thinking about the inverse idea: a small desk with a plain pine plank top with a sheet of acrylic over that. A large piece of paper between the two with schedule/calendar/mind map for a several month project written on it. Papers archived after project completed. Important changes noted by lifting the acrylic.
