Great capture, Brian ! ...I know just how hard this one was to pull off. Just after Christmas, we were in Myrtle Beach, SC, and visited the House of Wax. Some of the displays were illuminated with colored strobe lights. ...an almost impossible scenario to surmount when capturing the scene in stereo using the cha cha method. Actually, it was tough in 2D too. ...Also, a couple of years ago, we were at one of the Disney parks in Anaheim, California. I tried to get a stereo shot, another cha cha, of a ferris wheel which was very similar to the one that you posted. I forgot to bring my Cyclopital wide angle adapter for the W3, so a wide angle cha cha was necessary with my Nikon. I waited until the wheel stopped, but the lights did not stop flashing and changing color. To make things worse, the cars on the wheel kept rocking all the time the wheel was stopped. Some days, you just can't win.
