Through the computer, the internet and new technologies like AR and VR, the analogue world moves via screens into the virtual space.
The same is done by a hologram since it is a depiction of a 3D object encoded in a two dimensional layer.
All these technologies raise numerous questions, the most important being: What is the relationship between the depiction of reality and 'the real thing'?
Using holograms for jewelry underlines these questions since the hologram, especially when worn, will not always show the object it depicts. If it does, the appearance of the object will change with the light reflecting on it.
