What were the blue things on his tie?

All during the "speech to the nation" tonight, I couldn't stop looking at George's blue tie and wondering what the symbols were. Could they be some symbol that only Republicans can understand - that everything is alright really - or some symbol that only terrorists can understand, some hidden message like "bring it on" in terrorist symbols. Or could they be symbols that only millionaires understand, one of the secret symbols of the millionaire club. I may never know.
