Yes magmus, it's the red swirl, but look DEEPER into the swirl.. let it take you on a magical jouney thru never-never land, and then you'll notice that it's not only a red swirl, it's a bunch of torus's and balls that have a texture applied to them... and end up looking pretty cool
**EDIT** I also took my sig from that render, lightened it up a bit, and put some text and a border on it.. if I could remember what exactly I did to lighten it, I'd lighten the original render too.. but I'm stupid and always forget to save my .psd's
