Twin Screen Project Initial Idea

Initially I thought of doing something to do with constellations, and having an animation created on after effects of a specific star sign being drawn on one side and on the other side a live action film of a person to whom that star sign belongs and them doing an action that links them to their star sign.
I began looking at lots of different videos of constellations created on After Effects such as:

I found this graphically very interesting and I thought it might be something I could try out, and it also linked to the After Effects tutorials we had been given over the past few weeks, where we learned how to use shape layers and made things appear as if they were moving in across the screen. My thought was that it wouldn't be that much of a stretch to do from what we had learned and would be very visually interesting.
I soon moved on from this idea as it seemed very superficial and didn't stretch me creatively.
I began looking at examples of dual screen films and and other short films, and I came across some interesting films involving shadow puppets.
