Noticed the 2012 Olympic track and field finish has a shiny toy I haven't seen before.
There's a red box on the ground on the each side of the finish opposite their cameras.
It appeared at first to be flashing like a mirror until I saw it in slow motion.
They have a roll of paper inside with a motor driving it to provide a 'banner' background for OMEGA on all the still finish camera images.
