The installation reflects many of the Starn's photography styles, translated into industrial strength materials appropriate for high traffic.
There is a piece using translucent decaying leaf as the subject that is similar to the Starns' Black Pulse series.
The largest installation is similar to the Starns' Structure of Thought series. The originals are created by layering wax, encaustic and varnish. The subway version gives a similar feel (noted in the close-up photo), complete with the layering effect, though in this case under layers of some type of acrylic (my guess).
Not everything is familiar. The Starns include mosaic work and cut metal walls -- all tied together by the theme of nature.
The Starns were also featured in yesterday's New York Times Sunday magazine, where you can read about their huge contruction, Big Bambu, at Talix in Beacon, NY. We know Talix best for their works casting sculptures -- especially very large scale.
