For those having a layover in SYD look up at the Sky tonight
 

"The world may be facing its worst economic turmoil in decades, but the heavens are about to smile on Australia. A rare cosmic alignment tonight will produce a smiling face - or an emoticon, depending on your generation - high over the country."

I'm sure that anyone laying over in Sydney will have a smiling face regardless.

Wrong Base, only been there twice.

I saw the Northern Hemisphere version of this sight yesterday flying over the Eastern Med. While not a smiling face, it was quite impressive to see right as the sun was setting.
