Tiki has long been associated with the fine art of pinstriping.  You need only walk into a gallery like Kustom Lane in Hawthorn to see the worlds of Tiki and pinstriping walking hand-in-hand.  Poking around the internets recently I came across a most excellent flickr album with a wonderful example of Tiki artwork adorning some form of 4 wheeled transport at a car show.  The detail is just amazing:
