Were you pumping it up and down in the air?

No.
The incense was stationary.
A fast shutter speed stopped the rising smoke.

I see that, I was referring to it's tendency to form the ringlike structures, in still air I wouldn't expect that reaction from a column of smoke. Was there air movement?

I like the capture, btw.
