On the other hand, an app for your phone, or digital display placed by an artifact, it a bar code: could have as much detail as possible, with more and more in depth lessons that you can investigate depending on your own level of curiosity. (Or age.) A fantastic museum of the world - natural and human history in Ottawa, was great. But imagine, they have a diorama depicting a historical scene... Then there is a display counter in front where you can read what's going on in the diorama. Also a few selected elements from the display, shown behind that glass, but visible up close for us to admire. What is the description of a brass ring, in the display: "A brass ring."! We can see that! WTF? But we want to know: where was it found, what was it's purpose, why is this down here not something else. What era is it from? You could dig deeper: how was it made? Who made it? Where? With what technology? Brass? How did they blend the raw materials? Who wore it? Etc etc etc. A little electronic display could have that, It a link for everyone to follow - bar code for example we could scan. It could even link to a Wikipedia page, whatever. But, something! More than: "A brass ring"
