If you think that you have such Holography Technology, you need to take a look at this. It is the next level of Hologram display that can let you interact and feel it. Imagine a holographic ball falling onto your hand and you are able to hold it and feel it. Amazing? Video after the break.
This technology was actually demoed at Siggraph 2009 (on going right now). It uses 2 Wiimotes to detect the hand, a tactile display that uses ultrasound to give a push feeling and a concave mirror.
Take a look at this video and you will know what I am talking about.
