VRTC is a project developed with director J. Mikkelsen last year, based on the show performed in Barcelona on May. Yes, at the moment it features 15 minutes in virtual reality environment, just like the app BR (though BR is based on simple animations). VRTC can be watched through last generation phones by using any of the VR kits available on the market.
Last year we wrote about this project on our web page. It's in Italian language, but the built in online google-app translation may help to get the basic concepts (original English features are liked anyway). http://ow.ly/vlqg3063Rw4
There is also a latter interview with Miikkelsen: http://ow.ly/CnCt30bd2Wd
Anyway VRTC seems to be focused to the audiences at exibitions in VR / 3D field.
I couldn't listen to Brian this morning on BBCr2, so my hope is that a full video could be in the pipeline for a proper release (someone hinted about it last year from the States).
People who have experienced VRTC gave enthusiastic feedback.
