On Saturday special logo appeared on Google South African home page (www.google.za), developed to celebrate the Rugby World Cup. 

Google creates these special doodles in different countries to educate and promote certain meaningful events.
Dennis Hwang, a 27 year-old Korean is the official logo designer for Google and creates all Google doodles. Since the year 2000 Hwang has been designing brilliant Google Logo creations for all sorts of celebration days and fun events around the globe.
The first doodle was produced by Larry and Sergey, who, when they attended the Burning Man festival in summer 1999, put a little stick figure on the home page logo in case the site crashed and someone wanted to know why nobody was answering the phone.
