Here is something interesting made by an European company called Mindblowing, this is a three-dimensional model of a few buildings designed in AutoCAD and printed on special 2-dimensional surface, creating a 360 degree 3D-dimensional hologram like print that can be viewed without the need of any kind of 3D glasses. They utilize a technology called ZScape, developed by Zebra Imaging, and it sure looks really impressive, but is also quite expensive.
