Estrogen!

Unfortunately, it will be my only colour tattoo, because I had a hell of time healing that one. My body has rejected all of my piercings over the years, and clearly didn't like the colours either. It seems to handle blacks just fine though

I started playing in 1989, I've played every edition and even got published in a couple of the sourcebooks, so it was a good choice for a tattoo :)

I had a friend tweak it though so people who know Shadowrun will recognise it, but it doesn't look like a logo to people who don't recognise it
