... and some more.
To make this, I took photos of all the handwriting samples, then used #inkscape to convert them to vector images. I separated out individual characters, then wrote code to lay characters along line segments making up a hexagon tiling.
My idea was to have something that gives you an idea of notation used by mathematicians, but better than the 'cumulonumbers' nonsense you normally get.
There's just enough coherence to identify subdisciplines, but I didn't worry about keeping whole formulas intact.
I wanted it to have a dark background so it would look like writing on a blackboard, but I was told I can't print a 99% black page at A0.
Eventually, I want to put the original handwriting samples on the school website, along with links to the authors' homepages and short explanations of what they're about.
I learnt a lot about what my colleagues do just by asking them to write a line or two of #math!
There's an easy proof of this: you can colour the vertices red and blue so that no vertices joined by an edge are the same colour, and there are an odd number of vertices.
So any lap visiting each vertex once has to end on a different colour to the start.
Here's an image showing the colouring property, by David Eppstein. If you start on blue, you have to finish on red, and vice versa.
oops, just noticed I forgot to tag @11011110 in the above toot, for making that diagram. Follow him!
@christianp First reaction, the first two of the second batch.
@christianp I like the last one in these.
@christianp here I go for the odd ones, 1st and 3rd
