What the..? A vortex? O.k. ->Here is how this idea started out. :O)
1.Portrait compose a set of backlit open stairs.
2.Click shutter,randomly rotate the camera back N' forth on its axis.(handheld) stopping at different points along the 10 second shutter duration. Taken at night...What do you think? Abstract enough?

A one time deal...Totally experimental. I think I'll sign this one. Ha! :O)
