It’s a fairly large file and clocked in at 188MB. After it loaded, the Cardboard had seven VR applications ready for use.

  • Earth: Fly where your fancy takes you on Google Earth.
  • Tour Guide: Visit Versailles with a local guide.
  • YouTube: Watch popular YouTube videos on a massive screen.
  • Exhibit: Examine cultural artifacts from every angle.
  • Photo Sphere: Look around the photo spheres you’ve captured.
  • Street Vue: Drive through Paris on a summer day.
  • Windy Day: Follow the story (and the hat) in this interactive animated short from Spotlight Stories.

For anyone lucky enough to have used a VR headset, the experience will be an instantly familiar one. The app splits a first-person view into two screens, one for each eye, and accurately recreates that double-bubble view of VR screens. Next, the Cardboard viewer must be built.

Step 2: build the Cardboard VR headset

This is the fun part. By following the instructions over on the Cardboard site, the viewer can be easily constructed. Parts includes the cardboard, rubber bands, magnets, velcro, and NFC sticker and the lenses, which need to have a 40mm focal distance. Google suggests getting these off Amazon.

Step 3: get lost in a VR world

Place this ex-takeaway box on face, slap in an Android phone with the Cardboard app running and get ready for free VR. Google’s even opened up the toolkit so that anyone can create an app. Start “coding your own”, right here.

The Cardboard project comes from the 20% project over at the Google Cultural Institute in Paris. The 20% project simply means that a Google employee can dedicate one day out of their working week to create a new, fun or innovative project outside of the scope of their assigned projects. Or as Forbes puts it, “it gives them room to explore.” The Google I/O conference continues until the end of today.
