Danny Gregory sent me info about this dip pen demo. Jim Woodring made a giant nib (and holder) and then used it. We are talking GIANT. This adds to sketching completely new components: aerobic and toning! I'd have to go to the gym for weeks to be able to sketch with this thing for 2 hours. Can you imagine using it in the Sheep Barn at the Minnesota State Fair!!! "Excuse me sir, that's not shit; you just stepped in my ink reservoir."
Go check out the link because there is also a bit of video.
