Wow! That was fascinating and I remember turning my face again and again to the source of light rather than what was happening on the screen. The juggling rays of light and within light the smoke and the dancing of the moths were more enchanting for me as I do not remember the name of the film. Surely it was a black and white film.
Quite late in my life, I realised that it was a gift, I was bestowed that I was given an analytical mind who would look into the source of things rather than what was just obvious to vision.
