Maybe you've created your own AR program for wearables that shows the definition of a word when you highlight it IRL, or you've built a personal calendar app for your family to display on a monitor in the kitchen. Whatever it is, I'd love to hear it.

We recently remodelled our kitchen and dining area, and I wanted some art piece on the wall but couldn’t decide what. For months the wall was a little bare and we were having a lot of dinner guests. I realised our WiFi password was too complicated to keep reading out to family and friends so I built a QR code in Lego that automatically connects you to our guest WiFi. It looks good, and it’s Lego so it was a fun project with the kids. It took about 4 hours to build. The only problem was having enough 1x1 tiles to put on a 37x37 matrix.

Does this work for iOS yet? Last time I was trying out wifi qr codes only android handled them correctly.

Sweet! Now to make some qr art. My last iteration was an NFC sticker behind a painting but people have a hard time with that one.
