Her story

Lumo drifted into a radiology department through a storm drain and decided to stay, because it was dark, quiet and full of other things you could see straight through. She learnt to read films by floating over the radiologists' shoulders. Being transparent means she can't hide a thing, so she tells you the finding plainly and kindly.

She glows a soft blue when you get it right, which the radiographers find very helpful at 2am.
