Parallel. An animated font script for After Effects that is available to purchase at: http://aescripts.com/parallel-animated-typeface/
I made the following promo animation to show Parallel being put through its paces.
It was designed by me and turned into script by Tom Sikunas.
The finished font featured a complete glyph set of 72 characters. Not all of which are shown in the image above.
The font is designed to remain legible, even if you zero the line weight of either of the line pairs.
You can get quite a different style if you use the offset path button.
