passage of time
Leaves are a representation of time. As soon as you see a tree, you will know what season it is. With the change of color from green to shades of red, yellow and brown, it is autumn which makes us especially aware of the season. Those typical autumn colors are actually a transit color between green on its way to becoming brown. As such, you can also regard the autumn colors as an interface of time.
A collection of autumn leaves which have been dried in a press are being assembled with a sewing machine into one large sheet. The position of the leaves is defined by their color. By exposing the sheet to light, the expressive effect changes the vivid colors to brown. The sheet will thus be a "living painting", exposing the passing of time.
