awkawk media player
awkawk is a media player. The underlying motivation for its creation was the idea that UI clutter is the devil. It has a user-interface reminsicent of the SASAMI2K media player; in fact it uses graphics from that player. Screenshots speak louder than words:

User-interface during normal playback (there is none). After all, we don't want anything distracting us from Rachel, do we.

But when the mouse hovers over the bottom or top of the window, it magically appears.
