The 3D holographic display allows users to view and interact with virtual objects such as balls and blocks. The objects move and react using a physics engine resulting in a very realistic interaction and an almost life-like experience.
a hologram is a photographic recording of a light field , rather than of an image formed by a lens , and it is used to display a fully three-dimensional(3D) image of the holographed subject, which is seen without the aid of special glasses or other intermediate optics
We can also customise the course into teaching students how to do up interesting Hologram powerpoint presentation .

Picture: 3d PenThere is no software to learn or use, and there isn’t even the need for a computer. It’s a pen. It squirts out hot plastic like a glue gun, which instantly solidifies as you draw with it. The plastic even follows the pen when you lift it off a surface, essentially drawing into thin air. It’s almost like magic.
3D Pen Printer is pretty much the easiest and most fun way to get started with printing 3D objects. Of course, there’s still a little bit of learning involved, such as in holding and using the pen, and particularly about how the various plastic materials work. However, you don’t have to figure out how to use 3D modeling software which, to be honest, can be a lot more frustrating especially when you’ve never used them before.
