I wanted to capture a few common movements with my dynamic drawing (rotation, translation, growth/shrinking, color change). I also wanted to create a repetitive pattern that changed depending on what row it was in. My initial inspirations were a pattern with dots.

In this project, I explored geometries and mathematical aggregation of an ellipse to create highly articulated and complex patterns. Using a limited amount of code, the program is able to use the user’s input to create a variety of vibrant mandala like patterns. The geometry is calibrated to leave a perfect circle in the center of the canvas, where the text changes color according to the the lines that are being drawn.
