The blank canvas can cause extreme uncertainty. The picture has no form other than an intention, but the end result may diverge from the intention completely. As soon as the first mark is made, every subsequent mark is affected by the preceding marks (assuming that each mark is not completely random). The final image is the collection of the sequence of marks. Therefore it is the initial impact, the first mark that determines the entire course of the picture.
But what if the first mark is not perfect? In all probability, the first mark will be completely inadequate an expression of the intention or concept behind the picture. Each subsequent mark is not only made in relation to the first, but also affects the first, and is therefore an attempt to make up for the inedequacy of the first. Every subsequent mark is an attempt at correcting the mistake.
This picture was generated by asking an external observer to make a random mark on the paper. The random mark was necessarily uninfluenced by the philosophy of the picture. But the external influence was enough to start the creative process. To create, an impulse is required, a sensation must be experienced in order to react. Once the sensation is absorbed, it becomes affected over time by all subsequent sensations, in the same way that the first mark mutates over the course of the picture.
The picture is the combination of the marks, and represents the sensations experienced at each moment a mark was made. Therefore it illustrates the state of mind of the artist over the period of the picture. Every picture is a self portrait, a self reflecting image illustrating its own perception.
