Make sure to check out and download Packet Garden, a most excellent info visualization freeware program developed by Julian Oliver who seeks to "provide an alternative and accessible approach to visualizing daily internet use," by way of this experimental artwork.
Packet Garden captures information about how you use the internet and uses this stored information to grow a private world you can later explore.
To do this, Packet Garden takes note of all the servers you visit, their geographical location and the kinds of data you access. Uploads make hills and downloads valleys, their location determined by numbers taken from internet address itself. The size of each hill or valley is based on how much data is sent or received.
