SerialMapper has just published a blog on the use of the IPad for graphic recording with an example from my IPad recordings. I discussed IPad and recording with him in a Paris café the other day. But as he said, only time will tell if this technique has a real future.
Another interesting blog on this is from Ninmah meets World, a blog by Rachel S. Smith, Vice President at The New Media Consortium and a master of visual recording. There's a very interesting film about how to do recording on the IPad and even a few paragraphs on how to make the film! Quite impressive and very helpful in acquiring this skill. If you're interested!
