    I am in desperate need of resolution.

    Today I remembered a piece from a museum, probably about 7 years ago, which was what I assumed was a holographic projector, but my searching through google and wikipedia haven't brought it to light.

    It was a vertical mirrored tube with an object, a toy dinosaur, at the bottom. An image of the dinosaur could then be seen, like a hologram, at certain angles at the top opening.
    I then remembered a similar thing in a science shop, where it was a bowl, or two parabolic reflectors facing each other, with a hole in the centre of one. An object, again, is placed on the side opposite the hole, and an image of the object can be seen outside.

    Could somebody please explain this effect, as I can not find it anywhere.

    Thank you so much.

    I had one of those bowls, cant explain the effect but I can attest that the object you placed inside did "appear" at the right angle to be setting on a mirrored surface a top the "ufo" shape of the two dishes cupped together--when it was actually inside.

    I've heard of an MIT project on holographic projection, maybe it's the same thing. I can't remember the name though.

    Ha, I found it! Well, the bowl anyway.
    Would anybody know what this effect is called?

    hello!!
    i am student and very interested in holography.
    was introduced to this subject by one of my friends.
    hologramms are really magical i thing.
    was wondering if anyone knows where i can read about hologram history.
    how they were created and how holography was developing.
    maybe someone knows a book or a site where i can read a lot.
    unfortunately i lost contact with my "holography friend"
