The pink triangle was the symbol used by the Nazi's to identify gay men in the concentration camps. The black triangle was similarly used for other types of "social deviants" including lesbians. Today, the pink triangle and (to a lesser extent) the black triangle are widely used as symbols of gay pride. These animated graphics are designed with gay pride in mind. There are a wide variety of pink triangles using glitter patterns, multi-colored patterns, fractal backgrounds, as well as solid colors. We have also provided some black triangles. The color purple is widely used as part of the women's and lesbian movement, so we threw in a few purple triangles for good measure.Finally, the rainbow flag is also a symbol of gay pride. We've combined the two symbols and created a few animated rainbow triangles. These images are free for your personal use for email, your phone, or to post on any website, social network page or blog.
