Arcade Fire has just released the first song off the group's forthcoming album. Titled "Just a Reflecktor," the single is accompanied by a highly interactive video.

The video utilizes viewers' web browser, webcam and smartphone to enable them to control the view point in the video.

The webcam is used to track the physical position of the user's phone; using this information, the video then changes to show different parts of the screen as if they were being illuminated by the user's phone.

For viewers without a webcam, the video can also be controlled via the mouse, with the cursor taking the place of the smartphone.

The video uses JavaScript Library three.js, WebSockets and the open-source TailBone project and its effects have been broken down and explained by Tech Explainer at: justareflektor.com/tech?home

The band previously released a video dubbed "The Wilderness Downtown," which was set to the group's song "We Used to Wait" and was built using a combination of HTML5 and Google Maps.

The video can be found over at (ideally needs to be opened using Chrome).
