Look around stereo panoramas: drag, magic window, or a Cardboard viewer.
Turn your phone sideways and insert it into your Cardboard viewer.
Open a Google Cardboard Camera vr.jpg file, or any plain
equirectangular JPEG panorama.
or drag a file anywhere onto this page.
Photos you open stay on your device. Nothing is uploaded anywhere.
Move your phone to look around the photo. iOS needs your permission for motion sensors first.
