This is the stained-glass window from the Beatrice Webb House in Surrey, England, former headquarters of the Fabian Society. It was designed by George Bernard Shaw and depicts Sidney Webb and Shaw striking the Earth with hammers to "REMOULD IT NEARER TO THE HEART'S DESIRE," a line from Omar Khayyam. Note the wolf in sheep's clothing in the Fabian crest above the globe. The window is now on display at the London School of Economics (LSE), which was founded by Sydney and Beatrice Webb.
The window was officially unveiled by a ceremony attended by British Prime Minister Tony Blair, who is a member of the Fabian Society. 
Rick Warren sits on the International Religious Advisory Council, made up of members of the major religions. Its role is to advise Tony Blair on the work of the Faith Foundation.  This would explain why Blair decided to speak at the special forum at Saddleback.
