OK, so its not really a hologram in the strict sense of the word, but this completely blew my mind.
If we can do this today, imagine what a billion years of technology development could produce???io2technology.com said:IO2 Technology develops technology relating to next-generation interfaces some of which are not currently available, one platform is--the Heliodisplay.
Heliodisplay images are not holographic although they are free-space, employing a rear projection system in which images are captured onto a nearly invisible plane of transformed air. What the viewer sees is floating mid-air image or video. These projected images and video are two-dimensional, (i.e. planar) but appear 3D since there is no physical depth reference. While conventional displays have the benefit of being attached to a physical substrate, Heliodisplay projections are suspended in air, so you will notice some waviness to the quality of the projections.
The Heliodisplay requires a power outlet, and a computer, TV, DVD or alternate video source. The current version of the Heliodisplay projects 30" diagonal images in 4:3 and 16:9 aspect ratio. The Heliodisplay system is backward compatible and accepts most 2D video sources (PC, TV, DVD, HDTV, Video game consoles). For connection to a computer, the Heliodisplay uses a standard monitor VGA connection; for TV or DVD viewing, it connects using a standard video cable. The Heliodisplay is designed to be concealed (i.e. into furniture) and hidden out of sight thereby creating an unobtrusive display. Examples are shown in which the Heliodisplay has been hidden into a coffee table.

Although Heliodisplay images are easily viewed in an office environment, this system is unique, and therefore has to compete with it's surroundings, so contrast becomes paramount for optimal viewing. Having a dark backdrop or background emphasizes the contrast of whites and blacks and is highly encouraged when designing a location to view the display. The same concept holds true for existing physical displays (LCDs, Plasma's etc), but contain a high contrast background when the pixels within image are not illuminated. Also, just like viewing any computer monitor or TV, viewing a Heliodisplay image in direct sunlight is almost impossible. Images can be seen up to 75 degrees off aspect for a total viewing area of over 150 degrees- similar to an LCD screen. Viewing requires no special glasses.
The Heliodisplay interactive is like a virtual touchscreen for simple cursor control. A hand or finger can act as a mouse for cursor control interactivity in a computer environment. No special glove or pointing device is required. Just as you use a mouse to move the cursor on a traditional computer monitor, you can use your finger, hand, pen, pencil, scalpel, scissors etc. to move the cursor around on a computer environment (see: Images & Videos). The Heliodisplay connects to a computer (at least: Pentium III 400MHZ;25MB free disk space;Win2000/XP) through a USB port and standard computer cable.
