Going Under Sewage system art!

Once again, an example of using what's available to you. It's about creating a modern day Greek tragedy. This is what one South American street artist is doing under his hometown.

Jose Augusto Amaro Capela, aka Zezao, is a thirty-six-year-old graffiti artist from Sao Paulo, Brazil. For almost a decade he has used the sewage system of this overpopulated metropolis as the canvas for his spray-painted art. His trademark work is an abstract, complex and curvilinear shape; lonely, floppy and always blue. - via Huck Magazine
