I get that the background image is the "subject" image in the before and after SOPA/PIPA boxes...but I think for most people, it will look like content failed to load. Especially because the two (low contrast) backgrounds don't appear to be substantially different. I had to look it over twice to even notice a difference.
I had exactly the same reaction. I had to go back and forth a few times to see the difference. Perhaps making the transition more obvious with a fade or having the connecting paths be different colors?
