Formal Call for Napkin, Notes and Other Math Scribblings

Napkins are special: they are easily available in restaurants, cafes, and bars. While regular folks use them to make lists and progress on chores or get telephone numbers and progress human race, researchers use them to do math and progress knowledge. Somewhere between chores, race and knowledge, comes entertainment: there are napkin sketches, napkin writing, napkin art, etc.

I am very excited about math we do in scribbles, on pieces of paper we can easily find: napkins, receipts, business cards, or whatever.

So, here is a formal call for my pet project: please photograph or scan such gems, and mail (smewtoo@gmail.com) them to me, with your story, if you are willing to share, and I will collect them and create an online exhibition of how in these driblets, we force math and methods to progress.
