[DEVLOG] How QR codes work and how to generate them?

I had the best idea ever so I created a matching game, with QR codes. Which QR codes are equivalent? Can you pair them all?

In this video, you can watch the most important moments of creating the game, and also you can learn a lot of new and interesting things about QR codes that you probably didn't know! You don't have your phone with you, and you see a QR code somewhere and you are very curious what message does it encode? No worries! I explain how you can decode it by hand in a few moments (less than 0.000057 years). Or do you want to draw a QR code? I also explain the encoding, with a bit of Reed-Solomon error correction and other mathematical things, Galois fields and more...
