What the..? O.k. ->Here is how this idea started out. :O)
1.Portrait compose a set of backlit open stairs.
2.Rotate camera an additional 45 degrees left of vertical.
3.Click shutter, slowly rotate the camera approx 200 degrees clockwise(handheld) in 10 seconds. What do you think? Abstract enough?
A one time deal...Totally experimental. :O)
