Oh yes, I know what type of book you mean. They were kind of a big deal here in my teens, sold at every other corner. Now that you mention it, I haven't seen any in a while, but I do own one. It works for me only for maybe 2/3 of the pictures, the others I can't make anything appear in, no matter how much I cross my eyes. But those that do work are pretty rad indeed.
