Object Rotation

As the title says, It would be nice to 3D rotate Objects, for example, make it seem like crystals grow out of walls or Books are Vertically floating or have something on an angle as in Crooked

Currently, you have to have a separate object for Horizontal and Vertical items and that is if you can find both "states" for the object in question

For example: building a Book-case Library Dome is impossible at the moment (unless you want it to look weird)
Or posing a Pitcher in the Hands of an NPC-Model to indicate "Pouring"
