does anyone recognize this feature/effect?

[Todd Kopriva]

In recent versions of After Effects, I’d use shape layers to create those blue lines. But in After Effects 7 I’d have to use some solid-color layers with masks to cut them to the shapes that I wanted.

To get started with After Effects, I recommend that you start here: “Getting started with After Effects”

or you could achieve that kind of look using the pen tool to create the lines and applying the Stroke effect and some Glows.

In addition to glow, looks like the transfer mode was set to add/screen to give some pop to the intersections.

I would almost create a lot of those shapes in illustrator in advance as another option as well.
