Via the New Yorker on The Tree of Life:

Thomas Wilfred made art objects that mechanically produced light and color. Some initial research results:

A trailer of Lumia, a 2006 documentary by 13bits, a NYC production company. In the middle of the trailer, there’s a shot of a hard-edged kinetic light display that should appeal to graphic designers and motion graphic designers.

Documentation of Opus 147 on Youtube. Artwork produced in 1957, video shot in 2006 for the documentary above.

The Eugene and Carol Epstein collection maintain some pages with a bio of Wilfred, photo documentation of light displays, a cool cross-section diagram, and other resources. (Hooray for dedicated collectors!)
