My son wanted a cake that would look like a puck with the Montreal Canadiens symbol on it. Only, since his name is Adam, he wanted an "A" instead of an "H" in the middle. Here's how it turned out:
The cake is a chocolate, two layer cake. All the icing and the filling is buttercream except the "C", which is rolled fondant. I had extra icing so I did the fancy 3-layer deep shell border, but I don't think Adam even noticed it!
