Have never done it.
In my opinion, I like the natural looking fish, but thats just my opinion. If you do an albino tank, I would recommend a dark substrate, background, and decorations (rocks, driftwood, etc) to help contrast the fish. It might look really neat if you put it under the right light. Come to think of it, I think you have a really neat idea. Go for it!
Im not much of an expert on the different types of lighting, maybe someone can help you out, but something tells me that if you put the right light over a dark tank with white fish, you will get striking results. Since the tank wont look natural anyway, im not sure if you would want to go the planted tank route though. Might be an excellent bar room tank, or a tank in an unusual location where a natural tank would look out of place.
