One of the movie posters from Spider-Man 3 showed Peter Parker being taking over by Venom (i.e the black Spider-Man Costume which was really an alien symbiote.)
Cindy Dufolt decided that it be a wonderful image to turn into a cake. The one change that Cindy made is that she had Venom taking over Spider-Man, instead of Peter Parker. The results are wonderful.
Here is the side view of this Awesome Spider-Man Cake.
