The proposed Stop Online Piracy Act and Protect IP Act sparked huge protest across websites leading to a 24 hour blackout. But, how did sites visualise the protest? It is not an everyday occurrence so thought it would be interesting to see how some did it . . . and yes, blackout it was.
The concept is the turning off of a site, so the visual interpretation is turning off the light – well, it was for many sites.
I particularly liked the Wikipedia page with its short summary of what and why with simple calls to action.
