Close but not there yet: Interfering Sin Wave Pattern

sin (23.2 KB)

Hey Guys,

I’m attempting to create the wave pattern shown in the attached first photo. I can create ripples from sin waves and attractor points (see attached GH file), but they overlap each other instead of pushing against each other as it seems to be doing in the first photo. I feel like there’s only a small piece I’m missing here but not sure what it is.
