This fellow was seen using his clever homemade (apparently) stereo rig.
Obviously, a lot of effort went into making the whole thing as symmetric as possible.
I thought this was really cool, and wanted to ask him about it.
Didn't want to interrupt, but when I turned around a few seconds later, he had disappeared.
(Anyway, check out the bokeh on the spotlights. 60mm f/2.8 Micro Nikkor.)
