Shader to join two objects


I’m trying to make a patch where two objects (circles) are joined by a line, but I would like change this line to be different, with some shaders like electricity.fx in “user shaders”.
The problem is the “electricity.fx” just have one position, I only can choose one xyz, and I would like to define one initial xyz and one final xyz.

Can you help me?

I’m new here and I’m very interested in vvvv and learn!

Thank you very much!

Any idea?
Help me please!

I would like to make something like a line but with some shader or something more attractive…

Thank you everybody!
