Now here's something I bet your current cellphone doesn't do: measure the quality of the air around you and give you a full report. That might not be the case forever, however, as the Interzone designed by Alistair Bramley would do just that.

Designed as an add-on for phones, the Interzone would let you know when you could put the top down on your convertible and when it would be a smarter idea to don a gask mask and get the hell out of LA. How much such a contraption would cost is unclear, but if it's not too much we could start seeing things like this on phones in the not too distant future.
