Take the weboutside —and bend itthrough time.
Amy Erz turns real places into experiences you move through in time — bespoke, glasses-first, built for Meta Ray-Ban Display. Building on Meta's smart glasses since the platform opened to developers, and named by Lenslist as one of the early contributors to the platform.
I make webapps that take you outside — onto the events, the city, the street — and turn a single location into something you move through in time: what it was, what’s happening now, and what comes next.

Developer Spotlight: Amy Erz on Location-Based Apps for Meta Display Glasses
“Her work illustrates how the earliest Meta Ray-Ban Display experiences are not only about new formats, but also about rethinking how digital content behaves when it is directly connected to physical space.”
— From the editors at Lenslist
On Amy's place on the platform: “Amy Erz is one of the early contributors to exploring this area, building location-based experiences for Meta Ray-Ban Display.”
Self-initiated experiments — built to find out what a glasses-first web can really do.

Apple 50
Cupertino · WWDC
An unofficial companion for WWDC week, in Apple’s 50th year. The week becomes an event you move through: live keynote predictions stacked against the rumor mill and scored to the second the keynote begins, plus a patch hunt across Apple’s historic sites and the California places macOS is named for.
Stand where the movies were shot. Scenein surfaces hand-curated clips of films and shows filmed around San Francisco, pinned to the exact spot — with TMDB details for every title.
An unofficial heads-up companion for a BTS concert at Stanford. Attendees navigate the campus and stadium and ride the night with a spatial HUD built for the show.
My first Ray-Ban Display concept — born from a fascination with how Silicon Valley got built. A walking history of the garages, labs and milestones that made the Valley.
An unofficial companion to the Big Art Loop — San Francisco’s trail of monumental public art. The nearest of thirteen works surfaces as you walk, with the story behind each piece, the artist who made it, and a spoken audio tour in English, German or French. One build for every pair: the same webapp runs on Meta Ray-Ban Display and on Meta’s audio-only smart glasses, with no separate version for either.

Charter Day Trail
San Francisco · UN80
An unofficial prototype for the UN’s 80th anniversary — a self-guided walking trail of the seven San Francisco landmarks tied to the 1945 founding of the United Nations, from opening gavel to the signing of the Charter.
The rest of this site is glasses-first apps. This one is the web those apps live on — an independent aggregator that follows smart eyewear across every company building it, pulling the day’s headlines, official newsroom posts, prices and release dates into one place, with every item linked back to whoever actually published it. There is a desk per company, a developer guide comparing what each platform asks of you, and a buying guide that knows what country you are in. It publishes no reporting of its own, it is not affiliated with any company it covers, and some product links are affiliate links.
Independent of the companies it covers. Aggregates and links out; publishes no reporting of its own. Some product links are affiliate links.
— The throughline
A new way to experience a place — its past, its present, and what comes next.
Every project takes you outside and treats one location as something you can move through in time. Stand somewhere real and see what it was, what’s happening now, and where it’s headed — a new way to experience a place.
Past
What was here
Scenein replays the films shot on these streets; Silicon Valley History traces how the Valley got built.
Present
What’s here now
BTS Stanford rides a live concert in real time — navigate the campus and the night exactly as it happens.
Future
What comes next
What isn't built yet — the next place, the next platform, the next way to wear time. The work always leaves room for it.

— Approach
Two materials, always: location and time.
01
In situ
Experiences that only exist where they are meant to be lived — tied to a street, a building, a step.
02
Time as material
The past, rendered in place; the present moment, made touchable. History you can walk through.
03
Worn lightly
Built for a glance, not a stare. Glasses-first, web-native, and gone the moment you look away.

— Background
Years on maps and the web — UCLA Geography, cartography for Rick Steves guidebooks, GIS at Clear Channel Outdoor, web at The Washington Post — now building glasses-first webapps for Meta Ray-Ban Display, and named by Lenslist as one of the early contributors to the platform.
