Mark Gonzales is the author of this very crazy Circle Board, a circular skateboard that’s being ridden at New York by Anthony Pappalardo in this video:

Made for the Round n’ Round exhibit, at the Franklin Parrasch Gallery, it’s plain awesome!
But not being a skateboarder myself (though I had some fail attempts), the one thing that impressed me the most on the video was the black and white retro style with Jazz music, made by William Strobeck.
In contrast with the skateboard itself, it has all the mood from old movies.
