I was inspired by the post about Thore Husfeldt's sorting network on
stairs (
http://thorehusfeldt.net/2011/10/19/sorting-networks-
activity/). I wanted to do something similar for CS Education Week
this year (and did). Sadly it didn't get used a lot and I don't have a
photo with it filled. CS Ed Week happened during our final exams week
so traffic was light all week.
I did create a poster that I'm happy share. You can find it, and a
photo at
