The camera films a park landscape through the blades of a small, hand-built windmill. Each of the eight blades was covered in mirrored plastic. The film was shot on a windy day in the park, with three 100-foot takes being shot on the same day. The camera angle remained the same throughout. Variations in wind speed and direction cause a constantly shifting relationship between the landscape in front of the camera, as seen between the blades of the windmill, and the reflection of the camera with the landscape behind it. The rhythm of this movement between foreground and background is created by variations in the strength and direction of the wind.
