Thanks travis for the comment. Building it for the museum is a good idea. I don't know if all the museums have this barcode on the exhibits. Also, along with each exhibit there is generally a written description. But the problem is that its very long and no one cares to read the full stuff. So, may be the main focus should be to present the idea in more interactive way.
I guess the main point here is about to focus on a particular target audience. I will definitely consider your comment regarding this.
