Here's a great application of sketchnotes by MJ Valente to consider — sketchnoting documentary TV series. In this case MJ has sketchnoted the BBC's How the Earth Made Us series, episode 5.
This reminded me how just about any information we can watch, think about or experience can be sketchnoted.
Check out Maria's Sketchnotes set on Flickr for more of her sketchnotes.
