I believe it is hologram since the projection needs a wall or this particular screen in order to see it. This seems to be 3D.
This is, in fact, a projection.
It was created using a mid -19th century illusionary technique known as the “
Pepper’s ghost”, which projects images on to a plate of glass at an angle to create an optical illusion.
The illusion was created using Musion system Ltd.’s Musion Eyeliner projection setup.
