mikejuk (1801200) writes "Are we getting closer to really effective volumetric 3D display technology? A new display, designed in Russia, uses cold fog and a laser projector to create a volumetric 3D image that you can touch. A tracking device, and no it's not a Kinect, is used to detect the users hand and moves the virtual objects in response.
There have been cold fog 3D displays before this but this one has a reasonable resolution and looks near to being a finished product that could be on sale soon. Estimated price? Between $4000 and $30,000."
