One of Google's more exciting announcements at least year's I/O was Expeditions, a VR kit that let educators lead students on virtual field trips to far flung locales like Mars and the Great Wall of China. Now, you can add two more places to that list: The Great Barrier Reef and Buckingham Palace. The virtual Great Barrier Reef expedition was designed by none other than Sir David Attenborough and produced by Alchemy VR, while the Buckingham Palace tour was made possible thanks to the UK's Royal Collection Trust. There's even a YouTube 360 video of the Palace, so you can easily use your phone to take a private tour of the Queen's art collection.
