The Layar-sponsored augmented reality design class being taught this summer in California is still truckin’ along, so we thought we’d take this opportunity to share another video from the class.

This time we have a presentation by Layar artist Sander Veenhof, who is known for using Layar in his augmented reality art projects like the Pentagon/White House Infiltr.AR and the Museum of Modern Art AR “Uninvited” Exhibit. In this presentation to the students at Art Center College of Design in Pasadena, California, Sander explains his history as a digital artist using augmented reality, as well as his idea of “invisible augmented reality”.

He also talks about how he uses the term “Free-D” (instead of 3D) because technology has opened up a limitless world for expression. As for what exactly “invisible augmented reality” is, you’ll just have to watch his presentation to find out. So check out the video below to see Sander’s talk in front of the AR Design Class in Pasadena.

Layar is nothing without its creative and highly-skilled developer community, so we thought it would be cool to include some blog posts from the mouth of one of the most renowned Layar developers/dreamers/artists we know.

Sander Veenhof (SNDRV) is the man behind some of the coolest and most talked about layers including Biggar, The Game of Life, and the MoMA AR Exhibition. We asked Sander to write about his latest collaboration with Mark Skwarek, a guerilla AR campaign that launched Friday, February 25 (Stay tuned for video coverage from this event as well).

Tweeting to Obama but not getting through? Since February 25th you can now reach him right at his desk in the Oval Office. A virtual Twitter balloon has been placed inside the White House and another one infiltrated the Pentagon using the GPS-based Augmented Reality browser, Layar. The balloons display the latest tweets containing the hashtags #OvalOfficeChat or #PentagonChat respectively.

The placement of the two Augmented Reality balloons was the mission of infiltr.AR, a live augmented reality infiltration event orchestrated from a temporary command centre at Club Karlsson in Amsterdam. It’s the latest experiment in crossing physical borders by members of the Manifest.AR artist group, best known for their previous infiltration project: an unofficial guerrilla exhibition inside the MoMA NYC last year in October.

The virtual Twitter balloons inside the White House and the Pentagon can be seen ‘for real’ using Layar. Search and open the layer “INFILTRAR.” When not inside the two buildings, an ‘artist impression’ of the augmented space will appear, including an actual live copy of the Twitter balloon.

Since Manifest.AR members do not have press passes, and most probably never ever will, we are highly curious to see any screenshots of the virtual public message board inside the Pentagon press room, so journalists, give it your best shot! (And Tweet it hashtagged #pentagonchat please).
