Holus Tabletop Holographic Display
We don't have autonomous droids to treat us with holograms meant for some strange old hermit, but the Holus Tabletop Holographic Display is probably more practical, anyway. This desk- or table-bound box displays digital information from your PC, tablet, or phone as a holographic projection, with 360-degree viewing angles and four different perspectives. It can be used for everything from 3D gaming to holographic video conferencing, has built-in motion tracking and speakers, works with other devices like the Leap motion sensor and Emotiv eeg headset, and comes in two flavors — a Home edition good for most users, and a Pro edition for developers.
