When I was little my first encounter with digital drawing was with “Paint” on a windows computer, I always tried to fill in the white spaces of my drawing based on an outline.  In this stimulation, I wanted to recreate this childhood memory with the added touch of being able to see the process by “sending back the painted section to see the “holes” that I missed.
