An invigilator's job is to sit in the gallery when the exhibition is open.

For his next project, London-based artist Ariel Helyes invites everybody to take on this role in the chapel space of St. Margaret's house ... and get paid for doing it!

Visitors will have the opportunity to interact with the work specially created for this exhibition, accept the artist's conditions and work for him, and think about the role of time in the exchanges and barter that take place in art.
