This week’s drawing is a blooming flower. I had originally wanted to do something more complicated but struggled with the code as is. I had Stella Han help me figure out how to create boundaries so that when it hit a certain height it would shrink again. I also had Shovik Mani help me figure out a bug in my code. Originally I had posted the function for keyPress inside the drawing function and couldn’t figure out why it wouldn’t draw.
