The latest in saving the world through digital media and games: SharkBreak.
You can embed all sorts of widgets, usually with cute fish and messages about ocean preservation, onto your computer desktop. The catch line is that it gives you a “creative, fun, relaxing environment” that would hopefully encourage reflection about the marine environment, which is also often positioned as a space for contemplation and relaxation (see tropical island vacations).
Not sure how effective the message is (or if there’s really an educational component), but I applaud the effort, especially the small sea animals that follow your cursor around. Also interesting is the attempt to “wigitize” marine conservation – here’s an approach that embeds small pieces into your digital environment (shooting for ambience), rather than producing another one stop shot website for conservation information.
