You could use the illustrations you already have at first and comment and point to parts of the illustrations as you're commenting. And as you or a friend gets time later, you could make some of the illustrations video images. It would be interesting to me to see a video of a collapsing dusty plasma. Another video of electrons and ions leaving the photosphere and joining the solar wind. One of granules and supergranules. One of sunspots, maybe with planetary alignments and solar tides and S-waves.
