Blue Ring Symbol

You're looking at a cool blue, almost-closed oval shape set against a dark background. It's got a bit of a pixelated, rough edge, making it feel like it was quickly sketched out or maybe it's a retro-style graphic. The shape itself is very iconic, often recognized as a certain type of scientific gateway from a popular game, making it instantly familiar to many.
