One evening in Valparaiso, we saw one of the street artists at work. I imagine his work was unauthorized, as he was doing it at night. He had a big power spray paint gun, and wore a mask.
We got to see the finished image the next day.
Not one of my favorites, but interesting to have seen it happening.
Then when we came to Santiago, we were near the Fourth Annual International Sculpture Symposium. There are sculptures of various kinds all around a large park, but the coolest part is the big open tent where the sculptors are working. Whoever curates this event has chosen really interesting sculptors from all over the world. It was a treat to see them working and the finished works.
