SUST.org commissioned a great interactive game about sustainability, particularly housing.  It’s aimed at 9-13 year olds but I think I might give it a go myself as it looks like fun.  It’s called mysusthouse and the aim is to build a home that is as sustainable as possible, all within a £100,000 budget.  The game also recently won a Best Interative Media Award at the recent Scottish BAFTAs.
