I actually sorta kinda really love this idea.

This Philips non-spherical-biosphere is a self-contained farm for that produces hundreds of calories of various food sources a day. Its five-level design breaks down like this:

Levels 1 and 2: Plants
Level 3: Algae
Level 4: Fish and Shrimp
Level 5: Organic Waste

From what we can tell, the system is designed to cascade nutrients from the top to the bottom (back to the top). Optical fibers capture and redirect light to the plants during the day, while methane capture from organic waste can power lights at night. The algae create oxygen for the fish.(via)

Below is a video full of other ideas…not sure I like all of them but thought the little food probes that tell you about your food intake for the day might be a great way to learn more about health, I also like the idea of being able to see at a glance the carbon footprint of items you buy at at the store. Not sure I like the idea of a “food printer” skip to 7 minutes to see the biosphere.
