For my sketch, I used an image from Orientation this past summer:
I appreciated the variety of colors in this picture of myself and some great friends. I chose to create a dynamically drawn portrait that allows for a slightly modified outcome when the mouse is clicked. The sketch operates as it generates each frame, but each click produces a randomly sized target shape. This creates an oil-painting-like stroke when the image nears completion. See below:
