A great piece of work, I’m not sure if the developers or the kids enjoyed the experience more. Valve, the people behind some lovely video games; Half Life and Portal took the building tool behind Portal 2 into a classroom. Pointed some teams of 12 year olds at the basics of level design and watched them play. Inspiring stuff.
