Tony Stark, aka Ironman, constantly seen manipulating 3D holographic images and floating displays projected in mid-air from his phone or tablet. Unfortunately, the rest of us are not as fortunate because the current computer-generated holograms are too bulky to be integrated into our personal devices. However, if a team of researchers from Australia's RMIT University and the Beijing Institute of Technology (BIT) is right, we may all soon be able to mimic Ironman, at least, when it comes to playing with 3D holograms.
