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.
