So you drop two drops of colored water onto a sponge it makes two single spots on the sponge where they hit.
If you drop the two colored drops onto a puddle, the drops create a wave pattern that interferes with the other drop's pattern.
But if you send the drop through a net, you get a splatter.
I you dropped two close drops on the the net and then they continued to the sponge they would create a wave interference of the two splatters.
This would explain light as a "drop" made of many much tinier particles that stick together but span out when they go through a "net" breaking up into a wobbling "cloud" that is pulled slightly to where other light has hit previously. Causing the "self interference" phenomenon where light that goes through only one slot still interferes "with itself" as if other light (sent earlier) is still going through the other slot.
The way to test if the cloud is just gathering or getting pulled back together to a dot (in case of only one slot) is to remove the wavy target and put a fresh one (and a fresh two slots) in the path of the light that was being sent only through one slot.
Of course it fails, which explains why this is not a theory of anything.
This is useful. With an AI movie it could visually explain why the Heisenberg principle is reasonable (as reasonable as it can be) and necessary, and cannot be explained away as a reaction of the light to the environment.
