UbiArt UK demonstrates its Framework

UbiArt UK demonstrate their Framework tool (not available to buy, it seems) for silhouette films and games similar to Patapon

It looks like the software is storing a new layer each time the pen hits the pressure-sensitive surface or when the artist clicks a USB switch, automatically cleaning up each per-layer object, then probably linking the drawing to the objects in some way. So that when you click on a part of the original drawing, you can quickly swop it with a cleaned element and then rig it with a bone. I’m guessing you could probably do something similar with Toon Boom Animate and Photoshop, but it might not have the same speed and ease-of-use?
