Ninja dictionary

I empathize with the author in openculture.com, who said, it used to be such a torturous wait while looking up meanings of words in the 'famous' dictionaries of the net. I have had my share of twiddling-my-thumbs and waiting for meanings at m-w.com, dictionary.com etc etc. Enter the Ninja dictionary! I tried this out, and yes, it really is fast like a ninja. Try it out yourself here .
