Amazing building mapping

Seeper is a London-based arts and technology collective that explores "natural user interaction, responsive environments, devices and architecture to create multi-sensory experiences and memories."

That description doesn't do justice to their performance last October at the IAC building in Chelsea, NYC, during the Vimeo Festival and Awards celebration. Displays like this will be commonplace in cities all over the world well before 2050, and Las Vegas would be a perfect place for them.
