OK Go have some great music videos for their songs and this is my current favourite. All their videos ae original and don't stick within the boring conventions of most music videos. The video for "This Too Shall Pass uses the Rube Goldberg Machine which is a fantastic piece of engineering! There is even an interactive floorplan which shows photos and clips from the making of the video showing the machine in action. This post also relates to the 'What is a Line' brief as it shows the passing of time and calculations to make a sequence of events happen in a certain pre-defined order.
I think OK Go do something amazing in the sense that they appeal to such a large audience in their music videos. They are interesting and because they don't have a set convention for their videos, they are appealing for different reasons every time.
