Ron has posted a couple of nice videos, you may have already seen them, and I just talked with our local photographer about this very topic yesterday. It must be in the air. Check out Ron's videos here and Tom Mills "in-the-round" photography here.
As for the term deco-rotation??? It's just one of those words that have been formed from two other words and abbreviated. Like Ginormous! Like blog-cation! [Look here for a ready-search of blogcation]
It's just how we talk 'round here.
