Rings of Prometheus?

I was sent an email this morning from a reader who has spotted some interesting markings in the released Prometheus images. The markings represent some kinf of "Ring" structure. Not sure if you guys have found this or discussed it yet, but I thought it was certainly worth a mention. Here's what I was sent: [center][url=http://www.prometheus-movie.com/uploads/prometheusrings.png][img]http://www.prometheus-movie.com/uploads/prometheusrings.png[/img] click to enlarge[/url][/center] So what do you think? These rings are seen on the underside of the UFO-looking spacecraft from the trailer and on the ground of the planet the Prometheus ventures to. WHat are your thoughts? Thanks to reader [b]Vaagel[/b] from Norway for the image!
