1hr in front of the TV by bumblebee

"This is a simple, curious and imaginative experiment. On Christmas 2006, bumblebee (flickr name) decided to build a visual summary of his son, daughter and cat's movements in their living room over a period of an hour.

To have an accurate understanding of their paths in space he used a marked-out equally-spaced grid in masking tape and then filmed the protagonists moving across the grid for one hour. He then reviewed the video and plotted their movements on each minute of the video's timecode onto a 'room map' with corresponsing grid." check out his flicker page
