We're all concerned with global warming - right? Well, here's a site called Unscrew America. Designed and built by GSD&M Idea City (Austin, Texas) and the producer of An Inconvenient Truth, Lesley Chilcott it's a great looking flash site, with a catchy tune (I'm listening to it now). Supported by TVC's (starring PeeWee Herman - what's that about?) and print placements it's designed to get America unscrewing their old power hungry incandescent light bulbs and replacing them with energy efficient CFLs or LEDs. Navigation is a bit fiddly, but it's engaging and fanciful enough to keep you looking, and learning, and hopefully doing. Nice.
