I know it's off-topic as hell because it's not a reality render.. but it WILL be as soon as I can dream up a foreground that I can use this as a background for.  I wanted to make an ibl but this is not a fully immersive scene.  It's more a point of view scene and that doesn't work at all for a spherical ibl.  I DID however save the scene info as an hdr as well as a jpg.  Uploaded the full size render to my dA gallery as this one is huuuuge.  You gotta see it full sized to see how pretty it is for a first-ever Vue render.
