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.

Updated features include:

“Coordinates” is a new, ongoing, collaborative public AR art exhibition which invites the viewer to be physically present at specific locations. When viewers select this feature, based on their location, they will be directed toward artworks – translated into AR-- created by artists that activate the historically, politically or culturally significant sites they have chosen. “Coordinates” aims to inspire thoughtful dialogue and expand our understanding of public art.

Artworks may include sound so make sure to check for the sound button on the right hand menu when observing an artwork on site.

“Coordinates” will be updated frequently and will regularly include new artists, artworks, and locations.

More on the “Coordinates” project:

Invited collaborating artists choose their work of art to be translated into AR, where they would like it placed for its conceptual or historical significance, and/ or its relationship to the artwork itself. Each artist is credited as their image appears onscreen.

• The “News” feature

News will note new artists’ artworks and sites as they appear in “Coordinates.” Artists and locations will also be updated regularly on

• Additional VR/AR drawings update:

Users can pinch or expand Nancy Baker Cahill’s dimensional drawings and hologram to scale, rotate, place and record them in the environment of their choice. They can walk and teleport through her LA studio in 360 degrees.

Additional information:

Camera and video buttons allow viewers to take photos and record all AR experiences in any context, anywhere in the world. Photos and videos are automatically stored in viewers’ iPhoto collections when “Access to Photos” is enabled. Viewers are encouraged to share across social media platforms using the hashtags: #4thwallapp #Coordinates #4thwallcoordinates and any #AR iteration they choose.

Tapping on one Baker Cahill’s AR dimensional drawings, the Studio, or the Artist button in the menu, viewers will be prompted to gently move their phone left to right to place scene. Within seconds, the AR experience will appear wherever the viewer has aimed their camera. 

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

Enjoy the app in portrait or landscape mode! 


"I am excited to expand the 4th Wall app AR public art platform to include fellow artists I admire for their topical and rigorous work, who have chosen where they would like a specific artwork to be experienced in situ. I invite viewers to visit their specific sites and experience their works in AR.

We hope 4th Wall 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 smartphone or tablet. ​

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

Download it!

This app turns the accepted paradigms of fine and public art upside-down and backwards. The agency lies with the user. You choose how and where to experience this artwork. Refreshing, innovative, and fun. I highly recommend it!

Cool Concept if the App Stopped Crashing

So the app had a 5 star review, but only 22 reviewers, a little skeptical but I downloaded it anyway.. Ok, so maybe 2 stars is a little harsh considering the idea of it is actually pretty cool and different (no SnapChat filters here)... But, the app crashed within a few seconds of me applying any of the filters which was really frustrating. Hopefully that is fixed soon, and if so I will definitely be updating my review.

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.
