The QR code stool is easily one of the most functional QR codes ever created. This unique stool/light was created by Elena Belmann to see what a QR code would look like in 3D.
The QR code stool is made out of wood and can be either used as a place to sit or as a massive wooden lamp. According to Belmann, the stool can still be scanned, although she will not say what the stool's link leads to. QR codes are starting to appear all over the place. It could only be a matter of time before more everyday objects like furniture and packaging become 3D QR codes capable of being scanned. You can check out Elena Belmann's QR code stool here.
