3D Data Presentation and Information Storage

There are some patterns that with a slight blurring of the optical field can be made to appear 3D to human vision.   The Windows desktop pattern, "Greenstone" is such a pattern.  If you tile this pattern then look at it with a slightly blurred focus, it becomes a very clear 3D background.  Now imagine if instead of a tiled stone pattern, this was actually a pattern of things: books, buildings, stones on the beach, etc.  Now put some data tags on each of these structures.  You could "file" a lot of data for very quick visual cataloging or retrieval using such a storage technique.  You could also hide some data in a field of noise.
