On the shelves in my office were totem-shaped methacrylate blocks, placed diagonally. I always liked the prism effect they did.
One day I realized that by putting a light on the back, the effect was amazing, the light traveled through the methacrylate, but you couldn’t see the light source and there was a mirror effect on all sides that was beautiful.
When we were commissioned to design a bollard, we applied it to its central part.
A cylindrical cast iron piece finished in epoxy paint on zinc and cutting through that central axis, the large backlit methacrylate piece.
It is available in two sizes.
