The very same company that produced the M2 Heliodisplay mid-air projector has just come out with their latest project – the new M3/M3i Heliodisplay.
This nifty thing is basically a monitor that displays images in free space, just like those holograms of Princess Lea asking Obi Wan for help. With a viewing space of 30inches and a resolution of 1024×768, the display is quite blurry and not very stable. However, with advances this particular technology should become a big thing in the near future. Currently, this will set you back a very hefty price of $18,100 for the basic version and $19,400 for the interactive version.
