Look to the left of this post at the blue background, you'll see triangles floating among the outgoing spokes from the center of the webpage wallpaper. They match the art in the above image.
Is that an off-handed depiction of the Glimmer's triangular ships, or am I just misinterpreting digital art?

I'm definitely missing something here, where exactly did the name "Glimmer" come from?
