The Human Rights Campaign's logo supporting same-sex marriage, a pink equal sign inside a red square, went viral on Tuesday and turned into a meme by Wednesday morning.
HRC originally posted the symbol, a riff on their regular logo, on Monday, asking people to use it as their profile pic on Facebook. It soon popped up all over the social media site, and within 24 hours had more than 15,000 likes and 55,000 shares.
The release of the logo was timed to coincide with the Supreme Court hearing arguments this week in cases challenging California's Proposition 8, which banned same-sex marriage, and the federal Defense of Marriage Act.
Like any virus, as the logo has spread, it's evolved, as artist, activists, and even giant corporations have given it their own spin.
Bud Light made the equal symbol out of two beer cans, United Against Homophobia used wedding bands, and Martha Stewart served up a slice of red velvet wedding cake with the caption "Equality is truly sweet."
Former "Star Trek" star George Takei, who has a huge Facebook following and has been in a same-sex marriage since 2008, has posted different takes: Yoda, vampire fangs, Edward James Olmos from "Battlestar Galactica" beneath the motto "So Say We All," and Paula Deen astride two sticks of butter.
And then their were more organic versions, like a Passover-friendly one sporting two pieces of matzo, one featuring Grumpy Cat, one inspired by the work of Mark Rothko, a twist on the logo of punk legends Black Flag, and others featuring Divine, the Statue of Liberty kissing Justice, and the Impressive Clergyman from "The Princess Bride."
And yes, there's a bacon version.
