Anyone know how this effect might've been created?
The Okuda's told that they don't know for sure, but possibly "
but it looks like projected light, reflected off of warped/slightly wrinkled sheets of shiny metal or plastic. The reflected light is bounced onto a white wall in a dark room, and you film the reflected light pattern as you flex the sheet very slightly."
I gave that idea a try, but didn't get very satisfying results...
