Watch these 3D jellyfish holograms created with fans

I think your use of volumetric here is not a correct evaluation of the technology in the same way that you seem strident about calling out @AndreaJames for passing on a 3rd party use of the word holographic.

Volumetric has a very specific meaning in 3D and 2.5D visual production - the volume is the Z depth in X,Y,Z co-ordinates and the W depth in the U,V,W co-ordinates of non planar surfaces (UV the surface). Your lenticula work is essentially always 2d dependent on the Point of View of the subject - a nifty, yet sophisticated version of the old post cards that you tilt to get different images.

The image on @Faffenreffer sphere is essentially a 2D image that is mapped via a Mercator projection onto a sphere - no depth, no volume. Most often used inversely in planetariums.

Your use of parallax here seems non-standard and misleading in an interesting way. As this sphere is not reflecting light like any non luminous surface but projecting light from the LED’s you could possibly achieve a perception of parallax on a very large sphere or alternately film it on video with a wide aperture forcing the depth of field.

Ironically, to suggest the spherical persistence of vision model is “volumetric” is to almost suggest that it is holographic!

Oh I don’t know… as a fledgling piece of tech why cut off it’s legs before it has a chance to run! At $990 a 720x720 panel it’s pretty cheap in the LED panel world. Arrays suspended from ceilings in an atrium or other architectural interior settings could be a cool look. Maybe bullet proof the fan tech (fans have been around for a while) and develop the software into something DMX compliant for media servers and bada bing bada boom you’ll have nightclubs and hipster bars clamoring for them! :grinning:
