I'd like to set up the classic bookshelf secret passage in my house where someone can push a button on a bookshelf causing it to rotate to open. As a generic concept, I propose buttons than when placed on a deco object cause the item it is on to move or rotate (depending on the type of button). For example, I put my book case in front of a door I want to hide. I put a "button (rotate 90 degrees pivot back right)" on the shelf. When the button is activated the shelf rotates. Other button types could include ones that shift the object its width to the right or left. Even better if we can use patterns on the buttons. That way I could make this one look like a book.
