Thought this was pretty sweet invention, if your ever wondering how to get some of the nicest folds and bends with Acrylic then i would defiantly suggest this to help you out.
The man who made this made a work log you can find here. His work log is very detailed and will be very helpful doing this project.
You can also find his presentation with the link above but video basically says it all.
