When I saw the light-pixels build up on a darker surface at the start of a rendering, it reminded me of the Double-Slit-Experiment. So I thought by myself ,Perhaps I could get the same results when I set up the experiment in DAZ-Studio?".
I rang up Mr. Thomas Young to ask if he would be interested to repeat his famous experiment in 3D.
,Piece of cake!" he said - but it was only when he arrived in my laboratory, settled in an armchair, crossed his arms and shuffled his legs that I realized, he meant that literally.
Well, I got him his piece of cake with a nice cup of tea. And then he started to set up the experiment with the correct distances of cards and holders. After a while the typical pattern emerged on the detector card.
This picture was taken just in the moment, when he wanted to show me one of the pixels on its way to the slits - thus the wave function collapsed and we saw only the two stripes on the detector screen (second picture).
After he stopped observing the stream of light/pixels, the interference pattern showed up again.
(By the way: there are al lot of indecisive pixels flying around. I guess, they have bumped from the cards)

If you are interested in setting up the experiment yourself, here are some important measurements:
I have cut a hole in the first cardboard 1 by 1 pixel, the slits are 1 pixel wide and 196,4 pixels high, 1 pixel apart from each other. The candle and the detector card I got from a local hardware store, the cake came from Matousekphoto/sketchfab.
The distance of the candle holder and the card holders are circa one handspan.

Good luck with the experiment - and thanks for looking!
