This is a two-side mirror.

One side of the mirror has a hole on the reflexible surface.

"Visitor A is watching him or herself with the jewellery in the mirror."

At the same time, the other side of the mirror has a web camera that connects a monitor.

"Visitor B is watching visitor A through the jewellery."

When someone desires something, he or she is in the narcissistic mood. Through overlaping the experience of "seeing" and "watching others seeing", I offer the visitors a new experience of feeling desire, which they have probably already flet unconsciously throusands of times in their lives.
