Strictly speaking this may be off topic, but my interests include early optical toys, and I've just stumbled on a very unusual site which may interest others. It's ambitious, maybe so much so that it might not last, so you might want to check it out lest it disappear. It's "Mind in Disguise Designs" www.freewebtown.com/mind_in_disguise/papertoys.html. Lots of phenatoscope disks, magic lantern images, lots of digitized patent applications (going back at least to 1833) on all kinds of topics, the same moving toys from the 1920s from (I think) L.A. Times that are on the Barnacle Press site but digitized, some early Disney stuff. It's in progress, with lots of ideas about things to come.
