I'm  high school physics teacher and I was studying the topic "Energy and Heat" with my students when  I make this picture. The idea is to encourage students to see who is hiding behind the QR code in the picture.

This is a simple use of QR code, but it's works. The students were very curious to see who is in the picture.
