A surreal tidal wave as high as a skyscraper is about to bear down on this city and destroy it forever. No it's not ripped from the pages of a climate change report - it's one of the many worlds designed by British design student Jon McCoy, who revels in the apocalyptic.
Though McCoy has a number of paintings that depict cities falling into ruins, he also loves to show us structures that are being built - particularly in space or in extremely alien environments. I imagine that this is some kind of space dock and habitat.
McCoy's also loves to do concept design for characters, and this one caught my eye because right now Andrew "Wall-E" Stanton is working on a John Carter of Mars movie, based on the early-twentieth century adventure novels. You can see more of Jon McCoy's work on his website.
