Here is a picture tutorial for the internal  structure of my Princess cake with the moving swing and the flying carpet. Hope it will be of help to some of you in some way. You could try this or go one step further and make the swing automated  and  make it move at a press of a button 

etc…  Any questions please don’t hesitate to ask
