See that weird floating thingy in the air? Apparently it’s a design concept of a floating hotel, which, well, floats in the air from city to city. If it does become reality, it will run on hydrogen (drawing unfortunate comparisons to the ill-fated Hindenburg). For more info that I can’t be bothered to read, head here.
When I first saw it, I immediately thought of the Zendikar lands from the new Magic: the Gathering series.
Maybe the designers are M:tG fans?
