It's impossible to observe the museum especially if it's big one. You may walk through the galleries for days on end and haven't seen everything. Therefore it's very tiresomely and probably you will deny an idea to come back in a second day.

So I propose to invent a moving track through the galleries. Technically it might be built on basis of running track. People just stand on track and observe exhibits without any step. Such way visitors won't be tired and can observe more exhibits per day.
