Light holograms are commonly created in glass and lucite using lasers(the easy way), or light and artistic genius by such as Frederick Hart.
Using underwater lasers, create underwater holographic sculptures
Installations can very from lake or ocean size masterpieces to the acquarium novelty gift

can you explain the theory behind this a
little, I don't quite understand how it will
create a hologram and not just a bunch of
laser beams underwater. I like the idea if
you can explain. |
|
| |
I once went to a Fish concert, and there were many lasers. |
|
| |
Holography relies on capturing and storing phase information between a reference beam and an image. |
|
| |
Where is the storage mechanism in your system? Glass and lucite work well, as they are (essentially) solid. I don't think fresh or salt water will do the job.

Didn't the Irish do something like this in the Liffey in Dublin, with a digital clock, nicknamed "The Time in the Slime"? |
|
| |
They did this in Loch Ness. It worked! |
|
| |
Seriously, though, won't the movement of the water distort the image? |
|
| |
a nice thing to go with a multimillionaires pool |

you'd have to make the holographs underwater too unless you want to put up with a hefty blue-shift. |
