Clicking on the boats on this page makes them sink.

Loose clicks sink ships.

Odd analogy to tie-in to your event registration page. Sinking ships?

It's an easter egg. Sometimes a cigar is just a cigar.

Bit early to become Twitter? :)

There's also a Loch Ness monster too.

It looks weird that the battleship is moving backwards.

[rkroondotnet]

Every yacht seems to go backwards as well! Glad someone else noticed.

Not the tanker, unfortunately. That would have been fun to see go down.

Pop this in your URL with the tanker on screen: javascript:void(document.getElementsByClassName("tanker")[0].className += " sink")

Or, for those of a more surrealist bent: javascript:void(document.getElementsByClassName("fortmason")[0].className += " sink")

Try it on the "join" button and it "sinks" upward.
