I enjoyed last nights guest speaker, Joel S. Kollin. His projects stimulated the memory of a site I found earlier last year spotlight . It is an interactive project making use of light, sound and human behavior. Not “art” per se, but uses light and sound to move the experiencer outside of their norm.
I used to manage construction projects at SeaTac, some of which were in support of monolithic art installations. Most of these installations passengers passed without a pause. Think how much more interesting our journey would have been had we physical, interactive art instead. I personally think public art will best survive if it is indeed, interactive.
