///GRACE DAY TAKEN///

For this week’s project I took inspiration from the “golden angle” and natural angles of plants and things in nature from last week. I wanted to know what it would be like if I manipulated it to work through an angle of my choosing, and other aspects of my choosing, such as a plus shape instead of hexagons. I made the stroke weight very fine and the opacity more sheer to add added effects. I also introduced animation by incorporating variation with mouseX.

I think this design is interesting because as you move the mouse, it looks as though there is a flower itself in the middle rotating around and around, but really it’s just the shapes building on themselves. How interesting!

((This is unrelated but I went to the Children’s Museum today and saw the Letter Rain mentioned in the Deliverables for the week and that wE. cOdED. so I thought that was cool! Here’s a quick picture just for fun hehehe))
