"Reflektor"

Just something I stumbled across. Video for Arcade Fire's new single has been created with Google and other tech stuff to be user-controlled

"Reflektor" (which you can watch at justareflektor.com) takes user interactivity one step further, by having users effectively be the special effects editor for the video, using a mouse or a mobile device, and also using the computer's webcam. http://m.rollingstone.com/?redirurl=/music/news/inside-the-making-of-arcade-fires-interactive-reflektor-video-20130909

Info about the technology behind it is here, which can also be accessed when the video finishes (all 7 mins of it!)
