Very cool! While looking for more information on creating holograms I found this video - https://www.youtube.com/watch?v=aTB2ryoWIFU (from The Thought Emporium) on making holograms using the LitiHolo film, which looks really fun too, especially the RGB hologram.
Yes, this is the same film we use for the printers as well. It is full-color sensitive, so you can see where this could go for the printers after we get the initial concept off the ground.
