Brian Borrello's Silicon Forest (2003) is an abstract sculpture made of stainless steel and light-emitting diode (LED) lights, installed at the Interstate/Rose Quarter MAX Station in Portland's Lloyd District.[2] It depicts a series of trees with thin trunks and cone-shaped foliage.[3] The piece has been called a "three-part metaphor for displacement and change".[4] The solar artwork's steel trees illuminate using electricity powered by solar panels.[4]
In 2013, Solar Power World's Frank Andorka ranked the sculpture third in his list of "11 Must-See Art Installations, Inspired by Solar Panels".[1]
