Tech Level: Very Good
Making a video screen out of thin air
In a museum in Tampere, Finland, Ismo Rakkolainen's fog machine conjures up the Mona Lisa on an invisible sheet of water particles.
Thousands of miles away in Hermosa Beach, California, a graduate student passes his hand through an image of a DNA strand produced -- apparently out of thin air -- by a modified video projector.
The two inventions represent the latest front in advanced computer displays -- eliminating the screen altogether.
While unlikely to replace the desktop computer monitor, so-called walk-through displays could eventually be put to use in product showrooms, museums, and military training facilities.

I think that would be pretty cool, to actually see one of these things.
Just goes to show sometimes life does imitate art. Star Trek has used this method for years! After all what is a hologram (sp) on the show, but a computer generated image.
I find this amusing since now, nearly three years later, it is used on the show Bones as a way of displaying 3-D images of murder victims so that one can study their wounds and features for identification! What was once simply a Star Trek science fiction creation is now something real and plausible to use. While I have yet to see any type of home variation of this product, I have seen a larger version that is being used.
The name for this type of technology is called "Fog Screen" technology. It has been used in broadway productions for back grounds as well as to create the appearance of a vehicle coming towards you! In the last few years, the technology has come a long way from the Mona Lisa display a few years ago.
