This one has a lot more stuff than the last one, including a few "easter eggs".

If you're too lazy to find them yourself (I am), one is on the last page at the bottom right. It's an almost invisible button. If you click it, it plays a random song. There are six total.

Another one is at the top on pages one and two next to the button that plays the South Park theme song.

And the buttons above One and Two take you somewhere. Not really easter eggs though.
