sea/see/saw is a kinetic sculpture by Caitlind R.C. Brown and Wayne Garrett, constructed from 14,000 used eyeglass lenses. The piece was installed on the Pera Museum in Istanbul, and designed to mimmick a shimmering surface. The lenses were all donated by Canadian Lions Eyeglass Recycling Centre (CLERC) which helps visually impaired people around the world. These were lenses they were unable to recycle.
