A coalition of websites aimed at defending the freedom of the internet has launched its own version of the Bat Signal.
The Internet Defense League is made up of dozens of big websites - and thousands of members overall - with the aim of defending the "open internet".
Widespread concerns about the potential infringement on civil liberties by governments attempting to protect copyright or extend national security projects are among the concerns shared by a wide network of communities online.
The full list of current members includes Reddit, Mozilla, Wordpress, Fark and HypeMachine, and many more are expected to join before the IDL's official launch.
The League is intended to harness the momentum of January's 'Internet Blackout' which saw thousands of sites down tools for the day against the proposed SOPA copyright law in the US.
And as you'd expect, the League has some pretty cool launch plans.
So a the same time that the Dark Knight Rises opens around the world for midnight screenings, the IDL will project giant 'Cat Signals' into the sky, via powerful spotlights rented for the occasion.
The symbol, inspired by Batman but resembling a lol-cat, will be sent into the clouds in London, New York, San Francisco, Washington DC and Ulaanbaator, Mongolia.
Parties will also be held in other cities around the world.
"We are very happy to be sharing a launch date with Batman," the group said.
"Everyone who took part in defeating SOPA, PIPA & ACTA this year are legitimate real-life superheroes."
