I stumbled upon a new web site today that is just plain addictive: FreeRice
It offers a simple but addictive vocabulary exercise that's pretty much like the old Reader's Digest "It Pays to Enrich Your Word Power" feature, but with a catch: each time you select the correct definition, ten grains of rice are donated. It's funded by advertising and implemented by the UN's World Food Program; since its launch on October 7th over 263 million grains of rice have been donated-- almost 16,000 pounds!
