Have you seen this STOP SOPA screen today? Wonder where it came from? The man behind the screen is none other than Zach Johnson.  

On GitHub he explains: 

Hi, I’m Zach, and I made this for the internet. I felt inspired by the “going dark” theme of the SOPA blackout protest. I’ve been calling my representatives in Congress, but this gave me another outlet for my frustration with this legislation.

I place this code in the public domain. I require no attribution.
