For this project I wanted to loosely base it off of the eclipse mechanic I included in my Dynamic Drawing assignment, but still create a unique stand-alone image.
The shadow of the moon displays the time on a 24-hour cycle, eclipsing at noon every day, and all the colors of the image change throughout the course of the day in hue, saturation, and lightness. A lot of my process regarding this project simply came from experimenting and adding layers of elements to see what was effective.
Through the creation of this, I enjoyed being able to play around with the timing of my elements and seeing the little interactions between them as their cycles played out.
