The easiest Pepper’s Ghost projection screen to make is just a CD case lid pointed at a 45 degree over or under a phone

Is there not supposed to be a 3D aspect to this or am I missing something?
If you don’t look straight-on, wouldn’t you see 4 images ?

What are some good ideas to use this practically?
Use old phones plugged in with this device to show looping GIF forever, like a decoration on the shelf?
I have 3 old androids, wouldn’t mind some floating jellyfish in the living room…

Bingo. Do people no longer know what a hologram is?

That seems more useful than this kind of 4-way split Pepper’s Ghost, too. I mean, getting the Pepper’s Ghost illusion from every side is neat, but the novelty would wear off after a few seconds, and it’s all about the novelty. I’m not sure what you’d do with a single projection either, but it feels like it at least has the potential to be somehow usable; the 4-way split seems like it would introduce too many limitations.
