Tell us about yourself!
It's a reflection.
Good point! (And of course, it's still a cool little project!)
OK, enough. If you can't tell the difference between a movie screen and a mirror, or insist on using the same words for both, then we can have no useful communication with you.
A projection is a strong focused image on a scattering surface (like a movie screen). The image produced is two-dimensional, at the location of the surface, and may be viewed pretty much the same from many angles (just like a painting on the surface). A reflection is a virtual image created by a smooth (non-scattering) surface like a mirror. The virtual image is three-dimensional, located behind the surface, and provides a different view depending on where you're looking at it from. They are not at all the same thing, except that they both involve light and a surface I guess.
Yep, the Instructables email called this a "holographic 3D projection pyramid" even though it is neither holographic, nor 3D, nor a projection.It is, however, a pyramid. :)
