Has anyone made a sketch of the Heartbeat effect like the gate in stranger things?

I don’t watch the series. Got a video example of that? Nothing showed up on a quick Google search of “Stranger Things heartbeat”.

I made this in the past, but I have no idea if it’s anything like what you’re asking about. Maybe you can modify to your needs.

@marmil thanks MArc!
