I have personally made several interactive displays/exhibits for work. Yeah there are plenty of poorly made ones out there, but speaking from experience a good one truly does turns a museum into something a child is excited to visit. There is a reason why children's museums are made the way they are. Even children that are interested in learning, want to play. A great digital experience at a museum does wonders to bridge the gap between a regular museum and a children's museum. If a child has fun at a museum they are going to want to go back. If they keep having fun and keep wanting to go back, eventually they are going to start paying attention to substance of the museum. I agree great physical experiences are missing from many museums, but I'll happily continue to trick children into wanting to learn any way I can
