Chasing Rainbows

This is "Chasing Rainbows," which Villareal created in 2004.

According to the exhibition, "Villareal's early light sculptures were the equivalent of 'single channel.' But in 2004, more sophisticated custom software helped him to create Chasing Rainbows. This pivotal piece was a major step forward: 'I was able to see what I was doing in real time on the lights whereas before I had to go through very complex steps to see what I was doing. In a way, I had been working blind; it was like making a drawing with an apparatus that attached to your hand. I would have to go through multiple steps to make a mark, and then wait five to ten minutes to go see the mark. There was this huge disconnect between what I was doing and the results, because I couldn't see it in real time.'"
