//Draws the rain-like lines automatically
    push();

//Draws the ellipses with your mouse
    var mouseColor = jathryn.get(mouseX, mouseY); //changes color depending on where mouse is located based on picture colors
    noStroke();
    fill(mouseColor); //fills the circle colors according to picture color
    var ellipsesize = random(5, 15);  //randomizes the size
    ellipse(mouseX, mouseY, ellipsesize, ellipsesize);  //creates circles when drawing over
}

I wanted to somewhat mimic rain falling on a window so i tried to make it look random (since rain goes crazy in the wind) and then I allowed the viewer to draw randomly sized circles anywhere your mouse goes on the canvas, which was mostly for me because I was getting a little impatient.

What it looks like when I just let the rain fall

What it looks like after I started drawing circles to get the completed image

I was a little inspired by the post-expressionism art period and Van Gogh’s paintings and his swirling brush strokes to create this portrait. I think the most difficult part of this project was setting up the variables. Overall I really enjoyed working on this; I wanted to set up a for() loop to create the 10 spirals but in the end I was unsuccessful although I am still thoroughly proud of my work.

For this project, I created a computational self-portrait. While researching about data analysts in the past looking outwards assignment, I came across an image by dylan mason. Although this image was generated by compiling a lot of selfies throughout a long time, I wanted to mimic some of the qualities shown in this picture: horizontal bars and the balance between blurriness and clarity of the object.

Another inspiration for this project was the eye tracker assignment in which we used the brightness function. I implemented a hierarchical system, using that brightness function to make the width, length, outline and fill of the rectangles relative to the brightness of the color of each randomly chosen pixel on the canvas.

The brighter the color, the wider the width, the longer the length, the lighter the outline of the rectangles. The fill of rectangles are also related to the brightness. The brighter parts of the image are covered with light blue rectangles, while the darker parts of the image are covered with deep blue, almost purple rectangles. The rectangles on the darker parts of the canvas are smaller because I wanted a more detailed feel on the face area. On the other hand, the rectangles on the lighter parts of the canvas are bigger because I wanted to quantify and communicate the vast amount of light that is coming from behind the person (me). Bottom line, I wanted the attention to be drawn to the human figure more than the background and I believe I achieved that goal through elements, including but not limited to size and color.

In the first phase of designing, the there were a lot of overlaps among the rectangles that are derived from randomly chosen pixels. I wasn’t sure if I liked the aesthetics of it. In order to lessen the traffic, I spaced out the distance between the chosen pixels along the x-axis. Spacing out both in the x and y axes would have made the computational portrait a little too ambiguous.

To continue the language of horizontality, I drew a grid that consists of vertical lines that span from the top to the bottom of the canvas. Moreover, the change in color of these vertical lines (from red to blue from top to bottom) adds to the dynamics.
