Also digging the really mindf**k perspective. Looks like a super-tele lens with a lot of shift and it makes the stripes on the floor look really weird. Is the blur real DOF?
No. If memory serves me right that's gaussian blur I added in Photoshop. As for the 'stripes', I sharpened those for emphasis. Dunno about the lens -I invariably failed photography in school. I generally simply mess about with the SketchUp cam until I get something I like.
