Seeing as how there isn't a thread here for this, I'd like to take this time to shamelessly promote this free service powered by IBM. It's called World Community Grid, and it's a free service powered by IBM to help solve today's top humanitarian issues and environmental issues. It uses grid computing involving hundreds of thousands of volunteers from around the world volunteering their idle CPU time to computing projects that help both human species and environment we live in.
