Unlike artists including Robert Smithson and Mark Dion, who brought live or dead trees into white -
cube gallery spaces, Mr. Oliveira has constructed a tree from scratch,
using plywood and other materials, as well as wood brought from Brazil.
He also frequently
uses brightly colored vinyl tape in his site - specific installations, demarcating the
space of a
gallery and countering the austere white -
cube environment with exuberant color and unexpected materials.
