So this is my variable face program! It generates a randomly colored face making different degrees of the >:D emoticon, which is one I use a lot when I text. In addition, the face shape, mouth size, eye size, and eyebrow size are all also randomly generated. The character of the >:D expression changes a bit depending on the facial structure behind it, so I wanted to explore that aspect with this program.

For this project, I want to make different elements to change in a different way. I tried to make the distance between the end of hair end and headtop to maintain the same so I use equations to replace a single variable.

Using variables in this project turned out to be much more challenging than I expected. Many of the variables I tried to use did not initially work as I intended, and I felt like I was doing a lot more guessing and checking (similar to figuring out the coordinates in last week’s project). I had originally made a sketch of some of the kind of faces I wanted to make, but because I struggled so much with the variables, I ended up making a very basic face.

Biggest thing I noticed afterwards – didn’t draw any sketches. Using variables didn’t serve to just compact the code and make it easier to manipulate the visual with just a few changes, but also allowed me to make relative measurements as opposed to exact measurements for every conceivable feature.

	noseColor = random(["orange","yellow","green","blue","purple"]);
    //meanwhile, in a parallel universe where people's noses are a random color from OY G. BIV
    //and Rudolph, the only red-nose is their ruler
}

Disregard those two last comments in the code.

Besides the shape and size of the elements in the face, I also explored the variations of gradient and the effect it has on the visual appeal.

I created a number of variables as I built this face, inspired by modular 1960s design styles. After building the face, I spent a while experimenting with randomizing the size and position of all the elements and chose the three (eye size, pupil size, and eyebrow position) that I found most strongly affected the expressive qualities of the face.

With the face variable assignment, I utilized two portraits and adjusted facial features of each figure individually to make it appear they are having a conversation.

For this project, I focused on creating a bright, colorful mood playing around with different facial expression as well as warmed-toned colors.

This project was a lot of fun, I really like learning about how to make things interactive. It was tricky at first, but it became easier as I worked on it.
