I just checked over at the NASA Earth Observatory web site, and they have a new image up for today showing the massive amount of oil that is collecting around the Mississippi barrier islands. All the silver-ish swirls you see on the water is oil from the spill. I’ve downsized it from its original size. You can, if you want, visit this page at NASA to see or download the original full-sized image.
I’ll let the image speak for itself.
