Pixelated plotting

Movement Map: 1hr in Front of the TV, originally uploaded by the_bumblebee.

Here's a map that says a lot. There's an inverse relation between the value of the map and the privacy of the individuals whose movement has been plotted. Extrapolate:

A visual summary of my son, daughter and cat's movements over a period of an hour - Christmas '06. I used a marked-out grid and filmed them moving on video across the grid for an hour. I then reviewed the video and plotted their movements onto a 'room map' with corresponsing grid.
