This is a musing on what it might be like to see a pseudo-timelapse of the event.

I wanted to animate the background image and box shadows as well, but getComputedStyle was returning something funny with the colours, but I couldn\\'t work in out in time.

How it works: grabs all of the divs in the frame and applies default inline css values to certain properties. A transition is applied and the default styles are then removeded.
