Confess: You've played more than one hand of solitaire on company time. Maybe it's time to look for work with the Dutch Ministry of the Environment, where playing computer games could be part of your job description. The Netherlands is home to intense agriculture and industry, and is -- not coincidentally -- one of the world's hot spots for nitrogen pollution. A couple of Dutch enviro-heads decided the solution to the problem was to design a computer game that brought together policy-makers, farmers, industry reps, and plain old civilians to tackle the problem of nitrogen pollution. The result, NitroGenius, was unveiled last fall at the Second International Nitrogen Conference in Washington, D.C.
