this one was made for my friends son Kane i used a 10" can tin after it cooled i cut it in falf and filled with jam and buttercream. put it back together and after looking for a long time at my sons xbox cut into what will become the front and then the back of the cake cutting of a bit at a time untill it looked like the right shape i then covered the cake with buttercream.mixed up a grey colour in fondant and covered the cake using bits and peices i had to hand i indented the cake to look like the buttons.the vents i made buy pushing in the other end of a small paint brush while the fondant was still moist.the hand controller was made from fondant too.i had one close by so i could look at it while i was shaping the controller. hope this helps. nettie
