Echo / ohce

The public becomes the story ECHO/OHCE public installation. Portfolio images supplied by Georgie Pinn. A monumental interactive portrait that makes identity, empathy and digital representation tangible in public space.

The public opportunity

ECHO/OHCE extends Georgie Pinn’s touring ECHO practice into a large sculptural face. Presentations documented in the portfolio include World Science Festival in Brisbane and Melbourne’s Now or Never festival.

The experience

The public can capture and manipulate their faces in real time on a projection-mapped sculpture. The World Science Festival version is documented as seven metres tall. Intimate personal expression becomes a collective visual encounter.

What is documented

Source: Georgie Pinn portfolio/CV pp. 5 and 11; NUMINA 26 p. 9.

The giant head’s animation begins with the diverse cross-cultural archive built by the touring ECHO booth: over 40,000 captured faces and stories. Material from these intimate exchanges becomes mapped content at public scale. The archive total describes the wider touring practice, not attendance at one giant-head event.

Public value and next application

Outcomes to pursue and measure in a future commission

Visible public participation

People become part of the work rather than only observing it. The format gives civic programmes a concrete way to invite personal expression and explore who is represented in public space.

Learning through experience

A changing digital face opens discussion about identity, data and bias. A future commission could combine the installation with age-appropriate workshops and facilitated public conversations.

City identity and event engagement

The scale supports a shared focal point while personal portraits create visually dynamic moments. A future fan precinct could adapt this interaction into a collective portrait of the crowd, with permissions agreed.

Monumental and personal

The large face is visible across a public gathering space, while the interaction belongs to one participant at a time. This connection between public scale and personal agency is a distinctive part of Interactor’s practice.

Audience intelligence and business value

Audience intelligence: Understand portrait participation, chosen effects, interaction and viewing time, plus voluntary feedback on representation and cultural interests. Business value: Refine audience messaging and creative content; identify demand for future cultural experiences and relevant partner offers.

How to evaluate a future commission

Interaction patterns Count portrait sessions, chosen effects and duration; observe queues and access. Audience response Invite optional feedback on belonging, representation and preferred experiences. Follow-up permission Track explicit email sign-ups separately from portrait consent and participation totals.

A useful commissioning step

Agree the community purpose, sculpture format and site capacity. Define portrait consent, moderation, retention and deletion. Use an audience pilot to test accessibility, emotional response and the balance between interaction and public viewing.
