Mood Meter: How are you feeling today?

The origin of QR Codes and how to decipher them is simply fascinating. One of my students made me aware of this latest Veritasium videos and I am so glad they did. Learned a lot but I have to admit a lot of these went over my head. The evolution of QR Code is fascinating though and it’s an incredible engineering marvel in data science and communications. Appreciated the interview with the original Japanese inventor of QR Code Masahiro Hara, who was inspired by the Go Game. Can’t wait for color QR Codes in our future.
