I've spoken about artist David Kassan and his fantastic drawing and painting ability. I saw this video several months ago, and was astounded at how quickly he was able to adapt to a completely new medium that is technology-based.
This may not be the traditional method of creating art, but art it is, and I found it fascinating. This is where traditional drawing skill and high tech come together. This will be the new sketchbook of the future. Watch and marvel!
