Graphic facilitation and visual thinking is one of my personal interests. I’ve been reading up some a variety of topics. This community is very tight knit and there’s always a common set of players. One of them is Dave Sibbet of The Grove Consultants International.
Below is a very detailed webinar (90 minutes). I’ve watched the entire recording to confirm that it’s very valuable. I definitely recommend you watch it. Dave also demos Sketchbook Pro as a digital recording device.
