(thanks Chris Franklin) The World Health Organisation and the European Environment Agency have produced Honoloko, an enviromental computer game. Based on the BBC story description plus the image on their site, this seems to be a simulation game, with no right or wrong answers but just a playground where to see the impact of daily decisions. I can't wait to play it! (notice that I am well beyond the 10-14 age group that they are targetting. But, who cares!)
