Okay, this is obscure but personally satisfying.
When I visit Chicago, I enjoy visiting “The Bean”, the sculpture in Millenium Park officially named “Cloud Gate”. It distorts the skyline like a big fisheye lens. Everyone takes pictures into the curved mirror, getting curvy building pictures.
In Chicago with family yesterday, I packed my fisheye lens which distorts straight lines into curved. I pointed it at the curved image in the sculpture and the distortions cancelled each other out – but the lens curved the buildings at the edges. Kind of a reverse “bizarro world” photo…
Okay, maybe it’s just for me.
