Simple toy model to develop intuition for multiplying complex numbers. The grid shows the complex plane in the range -2.4 < Re(z) < 2.4 and -1.8 < Im(z) < 1.8. Move the yellow ball to any particular value of z, and the green ball will move to the value of wz. Press the space bar to select a new random value for w. Press c to toggle the unit circle.
