American rock band, OK Go, are in danger of becoming better-known for their videos than for their songs. The latest, This Too Shall Pass, took several months, around 60 people and more than 60 takes to realise. The result is an insanely good chain reaction filmed in a single shot. Put together in a two storey warehouse in Echo Park, L.A, the chain reaction machine was designed and built by the band, with the help of members of Syyn Labs.
Geek facts: The wooden tracks that guide the metal balls at the beginning of the video had to be waxed after each take to prevent dust from slowing them down, and the angle of the board had to be at a precise incline of 3.4 degrees.
The video has already had over 2 million hits on YouTube. See it for yourself.
