Afrum (White), 1966
Turrell wanted to give as much worth to light as people give to material objects. In his efforts to make light recognized as a medium, he's also meant to make it material and tangible. Afrum (White) set the precedent for the perception-straining light "objects." Two projected beams of light came together to create what appeared to be a floating white cube. Turrell would become so good at this practice of creating seemingly material things out of light that, during an exhibition at the Whitney in 1980, a woman leaned against one of his "walls" of light, thinking it would support her. She fell backwards, breaking her wrist. She eventually sued the artist.
