If you've ever heard the expression that a little can go a long way, then this site illustrates that principle perfectly.

You're presented with a word and four possible meanings for said word. Guess correctly and 20 grains of rice are donated to a community in need through the UN World Food Programme.

It's addictive too, so that 20 grains of rice soon becomes a sack full as you give your grey matter a workout and do some good at the same time.

Don't believe it? Over 37 billion grains of rice have been donated so far through this site.

Awesome stuff.
