John Baez added to graphic category some facts noticed at the cafe; I made left shelf a link and added the appropriate redirect to rack.
Thanks. At some point I added a proof that graphic monoids are the same as unital left shelves (a weird fact that interests me mainly because I’d never seen associativity derived using self-distributivity before), and a simple explanation of why presheaves on a certain 3-element graphic monoid are the same as reflexive graphs.
