Press the green flag and watch an orbital simulation. The purple square begins at the white square, and then after a small delay begins orbiting the green square with a certain velocity. See inside to change the initial velocity in the x and y components, and also drag the white square to change the starting point. Use the arrow keys to change your velocity, and the wasd keys to change your position. Press z to lower the pen and x to clear.
Double click the green flag when resetting
