Simon, Do you think the thing on this site is really possible?? http://www.eyetricks.com/mirage/ | ||

Well the box is probably lined with an concave mirror and all the light bounces hitting a single point recreating the object. (an example is simons hot dog cooker with the mirror curved in a parabola all the light hits one spot). | ||

You see these a lot in science museum gift shops. They have two concave mirrors, facing one another. The top one has a hole in the middle. They have nothing to do with holograms. | ||

I know how it works but why does the object get "re-created" by the mirrors? Shouldn't the light from the mirrors pass right through eachother? | ||

The device projects a real image at the top. The light does indeed pass on by. Read about optics, especially real images and virtual images. | ||

I just found this thing called the heliodisplay. True mid air projection, like Star Wars? http://www.io2technology.com/ | ||

find the thread on advancedphysics.org or slashdot.org yet? The screen is the operative element. Whether or not it uses a hologram/holograf is an aside. | ||
