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.
That is all. Tah chaps
