In the background is a representation of the sculpture called "Defense" by Henry Hering on the DuSable Bridge in Chicago.

The sculpture depicts a soldier killing Native Americans to defend the colonial settlers. In colorful shadows of more recent times, a police officer is attacking a protester proclaiming “Black Life Matters”.

This analogy illustrates the brutality of oppressing minority groups; a vicious circle in human history.
In addition the grid of Swarovski crystals represents the holographic quality of reality.
