	The middle panel of our Figure 2 is a reproduction of Figure 10 from [http://adsabs.harvard.edu/abs/1994ApJ...420..247W WTH94]. It shows the ''constant phase locus'' that emerged from the noise at late times during the evolution of four models: (a) Model '''O15'''; (b) model '''O14'''; (c) model '''E17'''; and (d) model '''E29'''. In the early '90s when this set of model simulations was carried out, we saved numerical data that detailed the time-evolutionary behavior of both the radial and azimuthal structure of each model's fastest growing eigenfunction. This data allowed us to generate after-the-fact, for example, plots of the ''constant phase locus'' at many different points in time to explicitly show how the azimuthally dependent eigenfunction developed out of the initial noise. Using techniques described in [https://www.computer.org/csdl/magazine/cs/2007/06/mcs2007060076/13rRUNvyaoN Tohline (2007)], we transferred these plots, frame by frame, to VHS video tape so that this development could be viewed as an animation. Recently we have employed an analog-to-digital converter to create digital animations from nine of these analog VHS recordings, and each of the animations has been uploaded to YouTube. (The result of these analog-to-digital conversions was, unfortunately, digital animations of low fidelity. They are nevertheless informative.)

Our Figure 2 displays a still image from, and provides a link to the YouTube animations that depict the time-evolutionary behavior of models '''O15''' (upper left), '''O14''' (upper right), '''E17''' (lower left), and '''E29''' (lower right); in order to play the desired YouTube video, click on the security-lock icon or the model name that accompanies the associated still image.
