Hey guys, glad you dug it.
As far as the camera rig/setup, all I added was a wide-angle lense - no adapter (wish I had one). All shot handheld. For the scenes with the 'ring' effect - we shoot through a black plastic tube to cut the light. Most of the video was shot at night, lit with a single beauty dish.
The grain in a few scenes came naturally as I played with he shutter speeds in real time as we shot. Focus effects just came from moving from manual/auto.
We had about 2.5 hours of footage, lot's of editing

- I'll see if I can upload a 720 version for you guys to check out.
I really had to do little adjustment to the camera.
