I haven't seen the August issue yet, but the application sounds both novel and effective.
In my opinion, however, there's something more timeless about the line drawings done by Oakes, Onosaka, and Kaufman.
Also, I still find line drawings to be better in eliminating needless visual elements(shadows, etc).
A side note: There is a feature on Corel Photo Shop that can change any photograph into an exquisite looking drawing. I don't know what to make of all this!
