The idea of a real holograph, a free-floating video image suspended in mid-air, has always been the stuff of science fiction. Usually not the near future kind, either. Movies that depict the use of holographs tend to be set centuries into the future.

Developed by Chad Dyner at IO2, the surprisingly compact Heliodisplay, which is about the size of an average PC case laid on its side (and only a bit noisier), is said to intake air, “alter’’ it, then expel it and use lasers to project the image onto the “still invisible’’ conditioned air.
