This is a weaving portrait of my friend Fallon. The color pixels will be concentrated on the cross between strokes of two directions

For this project, I used a photo of my roommate. One issue I could not solve was to adjust the size of the picture according to the canvas size, which is currently 3024 x 4032. Because of it, I do not think canvas is showing the whole image properly, which is why there are so many browns on canvas.

For this project, I used a picture of a friend sketching in her sketchbook. I decided to differentiate between interactions of the animation by using different text styles and words; the animation randomly generates the word “sketch,” but the word “doodle” appears at the mouse’s location, giving the animation some visual complexity. 

After looking through all the examples and code offered on the website, I decided I wanted to experiment with a number of designs. I decided I would do this by dividing up my screen and designating a type of design/pattern for each section. I was originally going to divide it up equally into three parts, but then I experimented a bit and decided to make it more interesting than that. I first decided to bring attention to my eyes by having the section over them be in HSB color value. Then I had there be two sections like this, one vertical and one horizontal, overlapping on one of my eyes, creating a cross section. This divided up the screen, and I filled up the sections this cross created with different patterns.
