funny logo of Google

I have just visited Google and found a very funny logo as below. The letters of “Google” are represented by Braille’s alphabet — a writing system for the blind. Today is Louis Braille’s , the inventor of Braille’s alphabet, birthday, so we can see such special logo on google’s homepage. I like Google’s lovely and special logos so much and try to do so on my former search engine project~~^_^
