On a related note, a really cool thing happened at a conference I went to last year -- there was an artist in the audience who sketched the talks as they were given to produce a single page thought-bubble summary!! They looked amazing, and generated a lot of discussion in the pub afterwards :)

Not sure if they're all online, but the one of me is here: https://www.filepicker.io/api/file/TIBDmf66Q5WPBF3ZBzKY

PS: Thanks re writeLaTeX -- exciting times ahead (we relaunched as Overleaf at the start of the year and things are growing pretty quickly!)
