Interesting work by Mathis Riehle.
Hi I have been developing this completely ignorant of sketchnoting as its own, mainly inspired by not being happy with normal liner notes, and the huge space and time required to do 'proper' mind maps. The B&W notes are all done as the talk is happening with filling in some detail and colouring as and when time allows. Online it went when I captured a whole meeting (in March this year). No real idea if it is good & useful for others or just pretty...
