Cool. Have you ever used the Manipulate[] function in Mathematica? It blew my mind the other day. You can just wrap any expression (including plots), with something like Manipulate[expression, {k, 0, 10}], and you get the regular output with a slider for k in the range [0,10]. If expression is a plot, it'll redraw as you drag the slider.
