I made a thing called 'Living QR code'. It's a QR code that consists of live webcam video but remains scannable!

I gave a demo during the lightning talks at #Hackaday Berlin: https://www.youtube.com/watch?v=BG1bW7P5s44 (my talk starts 52’44)

@tjaap It is fun, centre of each QR pixel is fixed, so rest can change. Last one I saw was Rick Ashley.

@tjaap Holy cow! This is basically magic at first glance, I love it.

@tjaap Reminds me of amazing-qr which works on similar principles but doesn't take in live video, that's impressive!
