In my class, we were talking about how modern artist used space in their images, in particular when using linear perspective. Our teacher took a brief second to discuss James Turrell and how he uses different contemporary mediums (in this case colored light) to defy the eye and it’s perception of space. For example, when looking at the red cube or the blue triangular prism, they might seem solid when in fact they are just light projected into space. Kind of sick, huh?
