White tree? or Purple tree?

The tree next door is dressed now.
The national art center is having an exhibition “Artist File 2009: The NACT Annual Show of Contemporary Art” starting from March 4th and this dressed tree is part of it. Those purple circles are originally white frisbees and they glow purple under ultraviolet light. It changes its color from night through a day depending on its exposure to UV rays.
Ladies, make sure you wear sunscreen!
