Tridimensional image gadget... can anyone explain ?

[Externet]

Greetings.  How much of it is illusion or how much is a real illusion ?  Never seen it before.  How does it work ?

There is a tiny video in the advertisement.  Does it mean only specific simple images tailored for it can be 'projected' or any images can ?

Thank you.

Of course.  But some odd out-of-the box uses/applications can bring a big smile for $5.

It is a version of Pepper's Ghost:

Probably you're more familiar with the 2d variety.

For 3D, you use multiple images to achieve the effect. Any image can be made to work though.
