Magneto - object placement widget

I need a object placement map built for my Magento web site. I need the customer to be able to place certain different objects into a map of our product so they can see the scale of the items in relation to our product before purchase. i.e. Queen size mattress. king size mattress, chairs, table, refrigerator, cot, dog bed. First version will be 2D second version will be 3D. The customer will get a outline of our product floor plan and then a menu of items they can drag and drop into the outline to create their own layouts and floor plan.
