Matt Shirley gets a lot of use out of his dry-erase board. He tries to make a new chart of some kind every day. He posted this one for back-to-school at reddit today, tracing the feelings of a child experiencing his first day at school. Another chart shows what that kid did all summer (and his parents).
Here's one that explains why your assigned seat in the classroom was so awful.
He also has plenty of charts that have nothing to do with school, but they usually pertain to something we can all relate to.
You can see all of Shirley's charts at Instagram.
