Here's my submission.
For whatever reason my iPhone deleted the [/img] I put at the end of the attachment. All fixed now.
Also, I believe Neil used a Nikon D90, boom, with 4 suction cups (two on the hood, two on the windshield). I drove the car in a circle in parking garage and that is what got the really cool rings in the photo. Hardest part was figuring out where to hold the steering wheel so that it got around all the garage supports without having to move the steering wheel at all.
