I got a small prism lens that clips on my phone. They call it a kaleidoscope lens but it’s more of a prism that repeats the center in a circular fashion. Tilt the phone and you get more of a spiral. Zoom in and you lose the prism and get the subject only.
I tried it on my iPad, but failed to center it properly over the lens so the images look cockeyed.
Here is the same window hanging taken with the iPhone.
I went out to a parking lot where I had views of the horizon and sky.
Charlie went with me. He does not like riding in the car but he gets scared being alone in the house.
