I stumbled upon this little site the other day. It serves a dual purpose, both to get people to bone up on their english vocabulary, while simultaneously raising help for hungry people worldwide. It’s a pretty cool, albeit strange, concept where you visit the site and answer english vocabulary related questions. For every question you answer correctly, the site will donate 10 grains of rice. The more you answer, the more rice you generate, the more free food goes to countries that need it. It works of advertising, as well, so be sure to click the little adverts at the bottom of the site for them when you’re finished playing.
