Really cool project! TIL about 'data:' URLs—while I was familiar with the 'data:' URI scheme and had used it before, I didn’t realize it could be used as a full URL. Funny enough, I had been thinking about building something similar that fits entirely within a QR code, but I held off because I mistakenly thought it would require an HTTP(s) link. I was heavily inspired by this work: Can you fit a whole game into a QR code?(https://www.youtube.com/watch?v=ExwqNreocpg)
