In Days Long Past,

I used to go to disco's,

 yes I know it sounds improbable, but there it was, I did, 

 and how did I know I was in a disco?

those multifaceted disco balls!

 so what happened to them, the disco balls, when the discos closed and opened up as bingo halls or health clubs?

 well some found their way here, at the Music Center LA in 2018,

Kyle McDonald and Jonas Jongejan filled a darkened room with fifty disco balls and created colored and timed lighting sequences to cast mesmerizing reflections that surround visitors, however, rather than simply relying on scattershot reflections, McDonald and Jongejan used hundreds of structured light scans to capture the volumetric position of every pixel being projected by each of the three projectors, the pair then used SketchUp to predict the reflected pixel positions,

based in Los Angeles, McDonald is an artist working with code, He has been an adjunct professor at NYU and an artist in residence at Carnegie Mellon, You can find more of his recent projects on his website and Twitter, Jongejan lives and works in New York City, where he is a creative technologist at Google Creative Lab, and previously worked in theater and television building interactive sets, He shares his work on his website and Twitter, I would never have thought of disco balls being used as an art form, but there it is.
