This is me last year dressed as a Medieval Minstrel, playing a Vielle en Rue, commonly (and inaccurately) known as a Hurdy Gurdy. This is in Warsop Hall, a medieval Barn in Nottinghamshire. We were holding a Medieval day for some of the students I teach pottery and music to. Everyone got freaked out at the orbs on all the photos, thinking there was some sort of supernatural activity. I just think its lens flare!
