<big>MIRROR OF VIRTUAL TRUTH </big>

An installation reflecting on internet trackers in a closed 
environment. It consists of a projection of virtual reality 
which shows how data about ones doings online is being tracked 
A display acting as a mirror shows visual presentation of how 
a persons data is spread around the web, displaying a conversation 
between the trackers with the data being pulled about a persons 
location.
