MIRROR OF VIRTUAL TRUTH

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.
