This is a view of a paved path in a park on an island in the Seine, photographed on a Sunday, in the early evening. The picture is split into two by the tree trunk in the foreground. It provides furtive views of people passing by.

Each half of the picture functions independently. There are three modalities for picture change, which can either be the same, or different, in either half: In the first, at any one time, one single image displays; in the second, two display, in a constant fade from the one to the other; in the third, a series of images mix together.

A clap by the spectator changes the current mode of picture change on either side.
