Glass dome, QR codes, what is this all about? A whole QR code house was built in one of Moscow parks. Almost all of its internal surfaces are covered with QR codes. From time to time they flash and light up in a random order to attract the attention of the
visitors. Visitors are being handled a handheld device to scan them with. Then they get some sort of information and other things through the scanned code. I don't find the idea to be particularly useful, however it looks pretty cool to me.
