Here's a couple of logo variations I made for the record label Dangerbox (which is awesome btw) Had them on my drive for a while forgetting to upload them here.
Not much to say regarding technique...just the same as every other 2D-3D conversion stuff you see, plus some chrome-ish highlights masked to the edge. One thing I will point is the use of Lens Blur as opposed to Gaussian. I highly recommend more people start using Lens Blur when faking DoF since it's the lens that causes it in the first place. Gaussian is nasty for depth.
