Watch these 3D jellyfish holograms created with fans

Bioluminescent jellyfish are just the start of what can be displayed with a hologram fan. YouTuber KLGadget shows how they work.

I saw a GIWOX hologram fan like the one above at a trade show last year. They are pretty cool in person and will probably pop up more and more for in-store advertising etc. Also popular with psychonauts!
