2 videos are attached to both ends of a see-saw set in the playground, capturing the blurred scenic views with ambient sound coming from the opposite ends in a continuous cyclical motion of ups and downs. One video captures a perspective facing the sun, while the other has its back to it; 30 minutes footage were recorded between 4 pm and 5pm on a sunny, breezy afternoon. The videos are connected to 2 DVD players played in loops, synchronised with a tolerance of 5 frames per cycle, displayed on 2 big projection screens.

Length of video: 27 minutes
