Chocolate Egyptian Cake

I made this cake when my 7-year-old sister studied Ancient Egypt. (I had made one about 15 years earlier when I was studying it.) It's a very simple cake, chocolate sponge, with melted chocolate icing on the top. The tricky bit comes when accurately mapping out the geography of Egypt. Now, apparently I didn't get it quite right, but who's really checking?

To make it yourself simply buy a Toblerone and break it into chunks to form the pyramids, make up some cream-cheese icing and add some blue food colouring and pipe away!
