As I sit typing this post, I’m listening to the Tragically Hip, downloading a 24 lecture series on Science to my iPod and I just listened to an inspiring speech by William McDonough (I highly recommend him as THE resource for environmental design). So I cant help but think of all the positive changes computers have brought around.
To add one more to the list check out climateprediction.net. Its a distributed software that uses idle computing capacity to predict the climate in the 21st centuary.
