4th Wall app invites you to walk and teleport through:

- Nancy Baker Cahill’s LA studio in 360 degrees

- Four of her original Virtual Reality drawings translated into Augmented Reality

- A hologram of Baker Cahill discussing her work.

Camera and video buttons allow viewers to shoot photos and record the AR experiences in any context, anywhere in the world. Photos and videos are automatically stored in viewers’ iPhoto collections. Viewers are encouraged to share across social media platforms using the hashtags: #4thwallapp #nancybakercahill and any #AR iteration they choose.

Tapping on one of the four AR drawings, the studio, or the artist button in the menu, viewers will be prompted to scan their environment. Within seconds, the AR experience will appear wherever the viewer has aimed their camera.

To teleport into and through the AR drawings, studio, or hologram environment, place finger on floor or where you want to teleport until starburst icon appears, then tap icon. Viewers can also walk through every AR experience offered.

To experience the hologram, tap “the artist” button and scan your environment.

To mute hologram, turn off phone’s sound button or tap the “home” icon in the bottom right corner. If you cannot hear hologram sound, turn phone’s sound button on.

Enjoy the app in portrait or landscape mode!


"In 4thwall, my complex VR drawings are translated into AR, so that viewers can not only place the works in their own “real life” environments, anywhere in the world, but are invited to record and document them in situ.

Led by their own curiosity, viewers may walk or teleport through my studio in 360 degrees and explore my 2D drawings and practice. In “the artist” section of the app, viewers may opt to experience an AR hologram of me discussing the conceptual underpinnings of my work and why we decided to create this app. We hope 4thwall inspires a new understanding and engagement with AR as viewer-driven “public art” and democratizes access to fine art in general, available to almost anyone with a mobile phone. ​

As an artist, I am always looking to expand and engage a larger and more diverse audience. Our hope is that viewers all over the world respond to the drawings and harness their own creativity to place them in all kinds of contexts. Art truly can be anywhere.

We are at the beginning of what is possible. With Drive Studios’ Creative Director Rich Lee and the innovative team at Drive Studios, I believe we have engaged the medium in a thoughtful and responsible way, and my hope is that others will do the same." – Nancy Baker Cahill

Amazing must buy


This is undoubtedly one of the greatest Augmented Reality apps of all time. The work is inspiring, the programming is flawless, and the hologram is straight out of Star Wars. Highly recommend.

Who knew art could be so much fun?


This thing is awesome. Interactive and beautifully designed and so much fun to play with.
