I have recently purchased a box of Hagoromo Fulltouch chalk, the so called "dream chalk". It has only been available for purchase in the US since spring 2012, but its merits have been known for longer. So heads up, heavy chalk users :) I'm posting because I am looking for a picture I thought I saw once that was "advertising" this chalk. It was a comical poster, with quotes like "proofs write themselves" and silly things like that. I saw this on the internet once somewhere. Has anyone else seen it? I would like to find the picture and print it out to "advertise" this chalk in my math department.
