Earlier this month we talked about a japanese company making green roofs, well now you can have the roof and the walls. Patric Blanc has mastered the art of creating green walls. His hanging garden walls are simply amazing, check out his website here (warning all flash). I am not sure how environmentally friendly these things are however as you would have to water them often, but if you lived in a suitable wet climate I would guess not that often. I see this more as an interesting way to integrate more plant life into our every day life.
