Honestly, it may be mine, too. I teach history and love having that on my desk. It's a shame how few teachers got it. But I love the light bulb moment when my students identify who it is when we go through Roman history.

My favourite moment was a visiting kindie kid playing with the pens, really in awe at the whole idea of it being printed. They took a pen out and put it back in, and I made a squishing sound, and they looked at me and said, "That's pretty serious."
