Our favourite design's include Massoud Hassani's 'Mine Kafon' which is a wind powered device for clearing landmines. As the ball is released over areas known to have landmines, it explodes any in its path and as an added bonus, tracks it's route via GPS.
Other rocking designs include virtual supermarket shopping via billboards in subway stations in Seoul. Just a click of the product image with your camera phone and the item will be on it's way home.
The show is on until 15th July and the overall winner will be announced in April.
