...Scanimation?
Rufus Butler Seder patented "scanimation" - an advanced technique of picket fence animation with paper & slotted overlay film. But how is it possible Colin Ord. was able to sell so many of "magic moving images" (book) without infringing the patent of Rufus. Also, there's another picket fence animation/scanimation product from P. P. Parmentier - how did he avoid patent infringement?
I want to use picket fence animation/scanimation - but I don't want to infringe any patents. Can someone shed some light for me?
Many thanks /
