3D QR Codes
In this exhibit, we're experimenting with the limits of QR (Quick Response) codes, in particular new ways to construct QR codes from physical material. Most of our QR codes are built from several layers of material (wood, paper, or acrylic), where each layer is a single color.
The QR specification defines the color (black or white) of each “pixel” by measuring brightness at the middle, where hypothetical grid lines would meet. This gives us room around the center of each pixel to change the color, and the QR code should still scan. This QR code reveals a famous mathematical puzzle, invented in 1924 by Henry Ernest Dudeney:
