Some recent articles on holographics got me thinking.

Tiny bubbles could lead to big advances in holography

Star Wars-style holograms one step closer to being in the palm of your hand

Suppose a low level light was shone at a surface such as a floor, then other colored lights were then aimed to intersect the light from the low level light beam, but not intersecting at the floor, but intersecting higher up the light beam.

The low level light acts as a way to get other lights to interact with it higher up.

Imagine looking at sunlight beaming through a window on an angle, you can see the dust glittering in the light.

So think of the dust as other lights interacting with the sunlight.

Could light interact with light like that? if so then still or moving 3D light pictures could perhaps be able to be created.

or lasers

shining colored lasers at a low level laser say an ultra violet one

the ultra violet laser acts a means for the other colored lasers to interact with it

think of a cdd detector that receives light

imagine a similar device that instead of receiving light transmits thousands of low level ultraviolet beams

while another laser device transmits thousands of colored lasers focused at the ultra violet beams

some programming would be required to match each colored laser beam to each of the ultraviolet beams

something like that
