So in short I have a circular mesh with “wireframe” checked in the material propreties, and I’d like to make the mesh go towards the center in an infinite loop (kinda like the classic retro neon grid but in a circle. Including my current nodes setup and a pic of the grid in question. Thanks in advance 
If you want to animate with materials I believe you need to have to involve delta time some how.
I remember in materials you use time to animate something.
Maybe look into a function involving water droplets and you’re looking for the reverse of rings being made.
