[ Overview ]

[ 101 malls · 48 countries · 1957 – 2023 ]

A portrait touchscreen kiosk for The Mall at Powerhouse, where visitors compare 101 shopping malls from 1957 to 2023 by form, size and place.

Mall 101 is the interactive companion to OMA/AMO's survey of 101 shopping malls, made for The Mall, the exhibition Powerhouse created with OMA/AMO. Led by OMA's Managing Partner David Gianotten and drawing on the practice's research in The Harvard Guide to Shopping, the exhibition looks at how the shopping mall evolved and what it has meant.

The kiosk puts the whole survey on one portrait touchscreen in the gallery. Visitors can spin a globe of all 101 malls, scan every plan at the same scale, open a mall's satellite plan, or set two malls side by side.

I built it as Senior Developer at Powerhouse: the dataset and image pipeline, the interface, and the monitoring and handover that keep it running on the gallery floor.

[ The Challenge ]

Make 101 malls from six decades comparable on one screen, for anyone who walks up to it.

The survey runs from 1957 to 2023 across 48 countries, and the malls differ wildly in scale, form and gross leasable area. All of it had to read on a single 1080 × 1920 portrait screen, work for someone in a wheelchair, and run unattended in the gallery for days at a time.

[ The Approach ]

A fixed portrait stage, one dataset, and every plan drawn at the same scale.

The kiosk is drawn on a fixed 1080 × 1920 stage that scales evenly to the screen, and a small state machine moves visitors between Attract, Map, Grid, case study, Compare, Find and Guide. MapLibre places every mall on a globe at its true coordinates, coloured by size and marked with one of five spatial types. GSAP handles the carousel and the motion.

Every mall has a satellite photo with its plan recoloured to the legend palette. The 101 photos and 303 pre-cut crops live in Cloudflare R2 behind a Worker. Tap targets all sit in the bottom 60% of the screen, within seated reach, and none is smaller than 62 px. A test script checks those numbers on every change rather than leaving them to review.

[ The Outcome ]

A kiosk that looks after itself on the gallery floor and says when something is wrong.

After 90 seconds without a touch the kiosk asks whether you're still exploring, then resets to the attract screen. It repairs what it can on its own, and the gallery player checks in with Sentry every five minutes, so silence is the alarm.

The kiosk build was frozen on 23 October 2026 and only changes through a deliberate redeploy. A handover site documents how to run it, and the same codebase carries a landscape browser version of the survey, parked for now.
