Very eagle-eyed of you Darque. I didnt even notice till you said, well anyway here's a screen cap, its blown up and dark so forgive the blurriness but it clearly isn't a swan
Looks like an arrow pointing up and down like a compass or clock. Note that it is different to the shark logo (seeming reversal of colours) and of course the swan.

The first site will cause the most confusion i think. According to message boards it changes a lot. If you mess around with the flash you will find more weird stuff
