Is acrylic glass the stuff that can be made into a thin film? I don't think subbed polyester is going to go away in the foreseeable future, but redundancy in any system is a very good thing! We're never completely out of luck, because I don't think regular glass is going anywhere, but I'd hate to lose the option of making film without resorting to subbing acetate (stinky process!! -- although it works fine.) Sebastian, Thanks for sharing your work. Cute monkey!
