          <p class="sample-text">
            This project, called Recursion Visualizer, is my final project for a
            Creative Coding class I took Fall 2021. It is a program written in
            <a href="https://processing.org/">Processing</a> that represents the
            way that I think about recursion, illustrated via coloring squares
            in a grid. This was my first time doing any sort of art with code,
            so it was a blast to create some fun visuals!
          </p>
        </div>
        <div class="text-left pt-5">
          <h3 class="text-heading title_color">A Visual Learner</h3>
          <p class="sample-text">
            I am someone who really needs to visualize things in order to
            understand them well. Whenever I try to solve algorithms or plan out
            a new project I try to write everything down and draw out pictures
            or graphs. When we were assigned to create some sort of "drawing
            tool" for this Creative Coding class I tried to think of what was
            most meaningful to me and what I found most important. I decided
            that for me, the perfect intersection of code and visualization was
            recursion.
          </p>
        </div>
        <div class="text-left pt-5">
          <h3 class="text-heading title_color">Recursion</h3>
          <p class="sample-text">
            The way that I tend to think of recursion is that you start with
            some big set, and then go down and down the stack until you reach
            the base case, at which point you go back up the stack with each
            level receiving information from the one before it. The first
            reucrsive bit is the overall grid, which is created by recursively
            calling a function that draws squares on smaller and smaller
            widths/heights, with different origin points. You can click the plus
            or minus buttons, or press "p" or "m" to increase or decrease the
            recursion level and make the grid bigger or smaller.

            <!-- Then, the way
            that the actual visualizer works is that when you hold down your
            mouse on a square it "grows" a square outward, ring by ring. The
            final grown square you get when you release your mouse represents
            the set that you start out with in a recursive function. -->

          <p class="sample-text">
            Then, the way that the actual visualizer works is that when you hold
            down your mouse on a square it "grows" a square outward, ring by
            ring. The final grown square you get when you release your mouse
            represents the set that you start out with in a recursive function.

        <div class="text-left pt-5">
          <p class="sample-text">
            Once the grown square has been created and the mouse is released,
            the "recursion" starts. Beginning with the outermost ring,
            representing the full version of the set, each ring is colored in,
            one at a time, to show the recursive calls getting smaller and
            smaller. Once the colored ring hits the center, representing the
            base case, a color is chosen and the recursive call stack begins to
            be resolved. Each ring is colored in based on the ring before it,
            resolving the recursive call stack where each call is based on the
            call before it.

            In addition to the pure visualiztion mode, there is also a fun
            rainbow mode that allows a bit more flexibility and freedom. In this
            mode, the rings are created based on where the mouse is and are
            colored randomly, so it isn't a great representation of recursion
            but its fun to play with and to create art with!
