If you’ve been on Facebook in the last day or two, you’ve probably seen a whole lot of red equal signs as people change their profile pictures to show their support fo marriage equality. ‘Equality’ was the top term buzzing on Facebook on Tuesday, followed by DOMA, and Supreme Court. Also on the list: Prop 8, SCOTUS and Defense of Marriage.

It’s been interesting to see the creative ways people are using the red equal sign in their own ways. Appropriately, Martha Stewart Living went the cake route:

The post currently has nearly 14,000 likes and nearly 16,000 shares. The profile picture is still Martha Stewart’s face, however.

The red equal sign image started with the Human Rights Campaign, which posted it on their Facebook page. It’s a play on the campaign’s logo, which is traditionally yellow on blue.

It’s highly likely that many of the red equal signs will continue to penetrate your Facebook news feed throughout today, as the court will hear arguments on the Defense of Marriage Act. As previously reported, a number of tech companies, including Facebook itself (and Google), have filed an amicus brief arguing that the act is bad for business.

Mashable, which pointed to the Martha Stewart image has a slideshow of various brands that are showing their support.
