Hak'u go to school

I was riding past an elementary school on the edge of the Stanford University Campus, and kids where painting figures on the wall. To me they all looked like Hak'u. So I asked the adult that was controlling the paint and paint brushes what the kids where painting. He said they where painting what they did over the summer vacation. I wanted to ask the adult if they had spent the summer inside a video game, but thought better of it.
