Introducing Complex Numbers

 I was watching an old OU video and there was a demonstration there that needed an update to geogebra - no need for hand animation any more!

The file allows you to take a polynomial curve and see what happens to the solution set as you move the curve vertically, demonstrating what happens to those roots in the complex plane.
