I'm HolographicDoll (also written with a space if you prefer). I'm a transgender enbie with major depression who likes computers, among other things. I've been around the Web in various incarnations since, oh, the late 1990s. This is just the latest one, and I hope it'll stick.
It was going to be Phantom Doll, after the song, but that was taken, and a hologram was still ghostly enough while also being a better fit for an online persona.
