When we were in Rio, we stopped at the Escadaria Selarón or Selaron Steps. The steps have been tiled by one individual who did it as a tribute to the people of Brazil. Jorge Selarón, the artist, was born in Chile and traveled the world before settling in Rio, in the neighborhood that contains the steps.
Originally a painter, Selarón first started the tile project on the concrete steps near his doorstep and then grew into an obsession to complete the entire stairway. And he has finished many times over. Now, once he finishes an area, he re-does another. His intention is for it never to be complete, a living artwork.

The artist is the guy in red. He was busy working while we visited and even invited us in to his house.
Our guide told us tourists bring tiles from all over the world. Next time we are back in Rio, we’ll have to bring him one.
