#Getting unstuck day 3. Two Sprites doing different things - I first thought of opposite things - like the Beatles Hello-Goodby song. Then I remembered this line of symmetry project I started with my math students. I was wanting to add a horizontal line of symmetry option. I found I couldn't set the variable to its opposite number (like set x = -x) so I check for the state in my forever loop. I had time to add other options- like color and pen size.
