"Six degrees" on the ant farm

Tweeted by @nicolasnova, have a look at this device from the MIT Media Lab, which takes social information created by you and I, makes it location aware and suggests future movement. Nova:

I would find interesting to have this sort of representation only as an ambient display at home: no mobile version, only some simple insights before heading elsewhere.

My first thought? The "proximeter" reminded me of an ant farm.
