Damien DeBarra was born in the late 20th century and grew up in Dublin, Ireland. He now lives in London, England where he shares a house with four laptops, three bikes and a large collection of chairs.
Looks like a lantern to me and being Brighton there’d be a nice coastal breeze to help them on their way.
