No lights, no camera, but there was action when Radiohead collaborated with Google to promote its latest video. For its song “House of Cards” off the album “In Rainbows,” the band made a video using lasers and computer data but not cameras or lights. Google is presenting the video, right, on its site (code.google.com/radiohead) as well as offering fans a short film to show how it was made. The search engine is also allowing amateur developers to download some of the data and create their own variation of the video under a license that allows remixes. According to Google, 64 lasers rotating and shooting landscapes in a 360-degree radius 900 times per minute produced all the exterior scenes in the video, which also uses 3-D technology. Radiohead released the “In Rainbows” album online in October as a pay-what-you-want digital download.
