"Aaron, thanks for the insight. Before we go deeper, I wish to explain that this is a conceptual idea meant to demonstrate my thought process. Nothing is set in stone. OK, now that that's out of the way, let's continue... As you probably know, QR codes aren't new at all, and it's not surprising that not everyone is aware, or let alone uses it. Because of this, we'll have to study how such tags would be adopted in the Singapore setting. Part of the goal of this gallery would be to keep traditional users, while finding new ones, who (for now until proper studies are conducted) could be young, mobile, and tech savvy. Visitors differ in levels of sophistication as well as expectations, and part of my job would be to engage each segment. From time to time I'll put out ideas which could be relevant for the library industry as well. Keep your thoughts coming :)" - Kevin Lim
