Does anyone knows how to make this kind of cake??? I'm thinking it´s about carving the cake and putting it together, but it seems a little more complicated than that. All I know is that it's a cake by Colette Peters. Any suggestions are welcome!!!

i had saw the cake,it is very beautiful.it may be of 2-feet long.yes I think the cake is totally 4 steps.they make the normal material of cake and after then they had arrange it in a order.Finally they had joined all these by the cream and decorating with chocolate flavor.
Really it is a complicated work,but a experienced person can do it cool.
