HI everyone, thank you so much for the positive response to this video. So many of you are asking for more information about lenticular imaging. I have decided to put together another video that walks you through (1) designing a two-image animation using digital software, and then (2) mounting the lenticular lens blank onto a printout of that animation design. I plan to post the video in September, so stay tuned!
You can't buy lenticular foil anywhere. It looks like a conspiracy, but you can really get them, for example, through a friend in the advertising industry, where the supply of these films goes. However, it is possible to provide stereo photos to an advertising company that will produce this for you. However, few advertising companies will produce one piece for you. It is necessary to search.
