I have had a structure for my film for about a month now, but had started to doubt what I had created. Last night when I started explaining it over to dinner to a new acquaintance, he rejuvenated and brought to light (no pun in intended!!!) what I had subconsciously created. After drawing it out, we could see that I had created a structure that oscillates back and forth between light and dark, just like a wave in a way (crests and troughs) and the wave slowly unravels as the film progresses.
