If you’ve just discovered my work through the Sphenomenon trailer, there’s a lot more to explore on my YouTube channel: years of concepts, prototypes, and experiments following that same thread: youtube.com/@gregmadison
That’s the thread from The 7th Sense to Sphenomenon: making ideas tangible so we can question, test, and share them. Objects become shared anchors for interacting with digital content, our surroundings, and each other. I explore future interactions with the tools we have today.
Thinking outside the box, within a box - 2013
My philosophy: reality is the operating system. The object is both the gateway to a digital service and its controller. Where we are, what we touch, and what we’re trying to do give intelligence its context. Information should appear where it makes sense, at the moment we can act on it.
Objects as gateways to contextual services - 2017
Across my creations, I keep coming back to one idea: everyday objects can carry digital capabilities. A table, a wall, a piano.. each has a place and purpose in our lives, familiar gestures, and a presence we can feel. Digital augmentation becomes a natural extension of our habits, without extra steps to remember.
VR Tangible UI - 2019
New follower? I’m Greg Madison. I’ve been pioneering tangible interfaces in XR for decades: making digital illusions part of the physical world, keeping us grounded in it.
A thread on the ideas behind my work. 🧵
Here’s an early exploration from 2009.

Seeing my friends and longtime XR folks genuinely smile and have fun with something I created brings me back to my years performing as a magician. There’s something incredibly rewarding about witnessing that joy firsthand. Thank you Storm, you made my day.
I just got back from @GregMadison's Sphenomenon demo & I can't think of a time I got that mind blown in the last 5 years. So, SO cool!! I am alive with inspiration. It was just magic, really. Joyous fun. Can't say enough good things. A must try if you can. Thank you Greg! 🤩💫
XR veterans are hard to surprise. Videos can’t quite capture what Sphenomenon feels like. These reactions can. Without excited developers, there’s no thriving spatial computing ecosystem.
@finkd @sama @satyanadella @sundarpichai @elonmusk @boztank @DavidSHolz want to try what got them this excited? I’d love to give you a personal demo.
I often feel nostalgic for the future. Tech has rarely surprised me since Ray Kurzweil laid out the roadmap back in 2005.

While in San Francisco, I finally got to try @GregMadison's mysterious and elusive demo on Apple Vision Pro.
I've tried a *lot* of XR demos and it was frankly one of the coolest and freshest things I've seen in a while.

I just got to experience @GregMadison's mysterious demo, and it's the freshest VR demo I've ever had.
It's brilliant, and has quadrupled my appreciation for modern headsets.
Everyone should try it asap!
