one day i kind of want to poke around with causing bruises via injection of my own blood into the parts of my skin that make the best bruises

also now I'm curious what happens if you just run blood through a tattoo gun. temporary, only a few months certainly, but no idea what it'd turn out like

@nire i would think it would be absorbed fairly immediately? i thought the staying power of tattoos was due to some extent to how our immune system responds to the foreign particles
