Here's a quick post - a wallpaper sized image you can download at 1920x1267 (click the image, or this link).
Full disclosure: this image is a composite of 2 panos shot at totally different times of the day. It would be great to tour lower antelope canyon during the night, but I don't think they allow that. It would be cool to try a shot like this for real.
For more strange shots, check out my Misc. Gallery - this is where I put the images that don't really fit into any particular category.
