Most AR displays and stops. This plays.
🎯 Roll a marble through a portal
🧩 Slide pucks to reveal a hidden image
💧 Tilt to slosh liquid, balance a ball
Tracked camera motion feeds a real-time physics engine — gravity & tilt actually move what's on the card.

No camera. No GPS. No app. 🔊📍
Just tracked indoor location using microphone — pure Web Audio API magic, runs straight in the browser.
Why not BLE? iOS Safari says no🚫
Why not GPS? Dies indoors📵
110 unique location IDs, tested for real🎯
Privacy-friendly too🔒

Most AR is built for one person. 🙋
But people rarely visit alone. 👨👩👧👦
CoQuest: a WebAR co-op game where 2 players are FORCED to depend on each other. 🔗
One has hints 🗺️.
One has the key 🔑.
Neither wins alone.
Two phones + on-device vision model 🤖📱.
#Designium
Most AR is single-player 🎮.
But most people at an attraction aren't alone, family, friends, couples.
Tested if one gesture: bumping phones together can carry co-op play: clapping, passing, key & unlock, cheers 🥂
Bump isn't the only element in co-op design though.
#designium
📺👻 Point your phone at the right spot and static clears into a yokai — an old TV finding its signal.
No app install to play.
On-device visual AI works indoors, outdoors, day or night 🌗.
Snap a photo 📸 before it fades back into the noise.
Built in-house 🛠️

Apple just made visual intelligence system-native.
The next challenge isn’t identifying what you’re looking at.
It’s deciding what matters.
RealityLayer explores that idea:
⚠️Safety
🏛️Culture
💡Insight
Three layers that surface context without overwhelming the user.

My Asakusa travel map
🔗tokyo-time-machine.vercel.ap…
My Asakusa by Sadako Sawamura, it’s a great memoir and I recommend it to anyone planning to visit Asakusa or Tokyo in general.
I made a map showing all the real Asakusa locations mentioned in the book, with page references & things to do. Try it out if you are in the area or just curious about the real locations of her stories.

Was testing how good body tracking on web actually is 🧪
Built a quick poc:
camera → pose → play (30+ FPS)
No install. Just URL. 3s start.
This might fit really well for
→ rehab
→ elderly care
→ HR wellness
Works on Mobile too👇
