Display continuos connection between 2 boxes

[reigj1]

Hi,

I have 2 boxes, I wanted to know if there is a way to display the boxes are connected and the connection goes from one box to another in a continuos way. Sort of like electricity. Is there a way?

Thanks

like this? https://codesandbox.io/s/splines-forked-3c7rg?file=/src/App.js though electricity sounds a lot more complicated and shader-y.
