The brief

Where it started

Twelve artists, one dark hall and a theme that is easy to make preachy. Hall Four needed a campaign that would reach people beyond the usual gallery audience, on a budget that ruled out most paid media.

The campaign had to do what the show did: make people slightly uncomfortable, and make them want to tell someone about it.

The idea

An exhibition about being watched should watch you back.

The work

What we did

01

Campaign

A poster series built on reflections, printed on mirrored stock so passers-by became part of the image.

02

Microsite

An interactive site that watches the visitor back, turning their own cursor habits into a short portrait they could share.

03

Launch

Wild-posting across the city and a single shareable link. Nearly all of the reach was earned.

In their words

The microsite made people uneasy in exactly the right way. We sold out the opening weekend before the reviews came in.
