Perhaps he can give us various versions of it including the correct digits? I think it's definitely on the right track. One with a line in the D, one with a keyhole, one with less light on the center, maybe less pale* etc, perhaps a slightly more 3D one with the D being more "sculpted" instead of flat, etc etc. Maybe we can have 2 versions, a totally plain 2D and the kick-ass-3D'er

* I did some GIMPing on it to make it darker / more sharp etc. 3 versions:
