Oh, wow! I was looking through some pictures that I took several months back and realized that I never posted any pictures of these cakes that I made.
This one is a baseball cake (I hope it is obvious, but just in case it isn't).
This is just a different angle of the cake (to show the ball in 3D a little better).
This one is a soccer cake.
I used a large rectangle cake pan and the mini ball pan that I used here (you can order the pan here). The mini ball pan was used to make the balls on the cake 3 dimensional. I thought that it added more interest than just drawing a picture of a ball on the cake with icing.
