This is probably the best place to post this image. I got frustrated looking at the eclipse through a pinhole, and all the TV coverage seemed to be in cloudy areas. (I did get a kick out of watching Jim Cantore on the Weather Channel struggling to find things to say as the sun was behind clouds during the totality period.) So I decided to see what I could get with one quick shot.
As soon as I took the camera outside it fogged up in the hot humid afternoon. I think the colors are caused by fog on the lens. The blue near the center, however, is the color of the sky this afternoon, and we had no clouds at all. If the yellow-to-brown vignette isn't from a foggy lens, maybe it's from a burning sensor...
I set my aperture to f/11, ISO on 64, shutter to 1/8000", and manual focus on infinity. I put the camera in live view, and when everything was ready I swung it up and across the sun, pressing the shutter at the instant I saw the sun on the screen. This is what I got. Pure luck that the sun is centered in the frame. This is not cropped or enhanced. Next time I'll buy a solar filter...

The camera still seems to work just fine, so I'm pretty sure I didn't burn it up or melt anything. Feel free to call me names and tell me that was stupid. I won't recommend this process to anyone else, but I like the result.
