As a young kid I had a periscope made from cardboard and a small mirror. I could look over the neighbours fence and spy on my brothers around the corner, it was awesome. I also love the ocean, so no wonder I was drawn to Australian Joel Adler’s Viewfinder sculpture. The angled mirror allows the viewer to look both directly out to sea and also at the crashing ocean below. Originally part of the annual Sculputure by the Sea exhibition in Bondi, the 6 tonne sculpture is now permanently located in Lighthouse Reserve, at Woollahra in Sydney, New South Wales. Brutal and aesthetically appealing from the outside too. Nice one Joel.
