Written on the body
Ariana Page Russell has a skin disease which enables her to write and draw on her own skin:
My own skin frequently blushes and swells. I have dermatographia, a condition in which one’s immune system exhibits hypersensitivity, via skin, that releases excessive amounts of histamine, causing capillaries to dilate and welts to appear (lasting about thirty minutes) when the skin’s surface is lightly scratched. This allows me to painlessly draw patterns and words on my skin, which I then photograph.
It’s simultaneously creepy and beautiful at once.
