Update: I've turned this into a web app!
This is a single line command to generate a "golden angle" animation by rotating an image in increments of 137.5 degrees. Try this out on images of pinecones, succulents, flowers, fruits, and vegetables – anything that exhibits fibonacci spirals. I'll post some examples in the comments below.
I came across this idea while reading about the artist John Edmark, who creates hypnotizing zoetrope sculptures. He said in an interview that you could take a pineapple or pinecone and put it on a turntable with a strobe light for the same effect, and I wanted to test it out.
