Here some visuals by Roger Dupuy about his "Bored of Boardcraft" talk.
Roger has also a nice visual vocabulary posted on his blog.
I'm a designer of English language teaching program that LOVES to sketchnote.
The link provided are samples of my 'work in progress' learning about visualizing ideas. I use paper and pen, but sometimes PAPER (by 53) on my iPad. I am a fan of MR's work.
I will be giving a talk called "Bored of Boardcraft" which is targeting language teachers who want to learn about how to teach using sketchnoting techniques at the TESOL international conference this March.
Here is a link to Bored of Boardcraft .
I'm sure your talk was a success!
Thanks for sharing with us Roger!
