The board seen from another perspective. The colours cannot be discerned
too well, but the scene looks nice. This kind of a depth of field would 
be impossible to achieve with a normal camera because of the inherent 
limitations all physical lenses -- only a pinhole camera has a depth of 
field extending from the camera to infinity, but it's resolution is
diffraction limited. For me, ray-tracing is also a way of emulating an 
ideal camera with an ideal lens having no geometry errors what so ever.
