Augmented reality 'easter eggs' to hunt down at Coachella this year

Offered to all: Coachella is already sold out, but the app is not uniquely for the festival's attendees.

Coachella is amping up its app's virtual reality features using augmented reality technology.

Last year, for its 2016 edition, the Coachella festival introduced a virtual reality app on which festival-goers could use a cardboard headset and their phone to view enhanced performances, 360° panoramas and tours of the festival grounds.
