Saturn would be tricky because of the rings, but I'd love to do Jupiter! It might even look like a static image unless the red spot were in view, but when it appeared it would freak some people out I bet. :D ...Like the statue that suddenly blinks at you!
I'd love to increase the color saturation and contrast (even though it probably wouldn't look as natural), but editing webp files is proving harder than making them to begin with. :(
