I know there have been funnily labeled links around for a long time, such as "click here to start". The difference might appear subtle, but I believe this is quite the opposite of a button labeled "get started": one is about the computer, the other is about you, pressing the button.
Another example: a link labeled "biggest idiot ever" linking to a politician's web site is an expression of the link's author about the target location, using the power of the link to change context—quite classic hypertext technique. A button labeled "explore" on the other hand is about you, clicking that button to bring yourself into an exploratory mood before being presented with new information.
Maybe also related, "overlay scrollbars", the thin lines on the right side of windows and screens serve as indicators what portion of a document a user is currently viewing. They are not a tool for scrolling, as the fully formed scrollbars with arrow buttons, tracks, and drag handles. They are merely a prompt for the user to do the scrolling themselves.
We are an instance for discussions around cultural freedom, experimental, new media art, net and computational culture, and things like that.
