Use the following keys to control the geometry: ----- up / down arrows --> change the number of sides left / right arrows --> change rotation angle space bar --> reset to beginning values Mathland Project Ideas: Create your own, unique geometric playscape where the user can change some value(s) using the arrow key to control the drawing geometry.
Sometimes I never quite know what I am going to get when I start to program some pen drawing geometry. It's a bit like writing a story and you don't know how it will end... (If you find some interesting values that draw interesting designs, leave a comment below saying what they are. One of my favs is rotation=18, sides=10) Check out rotation = 0, sides = anything
