Denise Jiang- Project 09

Drawing the pixels of a photo of myself, I set the circles into random sizes. I took out the pixels of the eyes and made them flashing. Basically, it erases the pixels on every other second, and then tries to redraw. The mouse also functions as an eraser by drawing random sizes black circles.
