I liked this one the most out of the ones we had.. though I didn't use a bevel tool to make it. I created a heightmap and shaded it in a few areas and used photoshops lighting effect. Then layered it with some internal reflective layers. The G was actually formed by the negative space caused from two solid pieces that never actually touched.
At this point I'd love to see ideas that think entirely outside of the box and not make it a G at all.
