The lighting concept is specifically created for the sculpture. My own idea to enhance it, is that the light on the chairs changes slowly, almost imperceptibly unless you stand or sit there for a long time. The table with the fixture underneath is where the power from the underground (the curry cross) comes up and should be a bit like a campfire or an energy hole where energy radiates.
I envision colors that reinforce the stones but still give energy even to those who pass by.
