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.

Food Replicator

Ok, not really a Star Trek Food Replicator.  But close.

Step 1:  Package food: meat, vegetables,  in sous vide packaging with either refrigerator-readable 2d bar codes or RFID tags.  These would be sold frozen.  They can be purchased and loaded into specially configured freezers-cookers. Requirements: standard packaging; automation readable labeling; appliance for storage (more requirements on this to follow); supplier of said packaged foods
Step 2. Based on a selected recipe, the appliance would select the appropriate packages from the freezer section.  These would be cooked sous vide for the appropriate serving time.  Requirements: appliance that can catalog, select vacuum packaged food; requirement to sous-vide cook said packaged food; ability to cook several food packages potentially at different cooking times; ability to open and serve different food packages onto serving plate.

Differences from Star Trek:
* food takes a long time to cook -- you need to select in advance
* food does not get created from nothing -- you need good wholesome ingredients here
* food tastes really good :-)
