UnrealArt is artwork based on gameplay in Unreal Tournament.
All artworks have been created using data from the game "Unreal Tournament".
Each image represents about 30 mins of gameplay in which the computers AI plays against itself, there are 20-25 bots playing each game.
The Bots play custom maps I create. Each map has been pathed so that the bots have a rough idea of where to go in order to create the image I want.
While this is architecturally / location based, graphically it is compelling if manipulated (e.g. "Each map has been pathed so that the bots have a rough idea of where to go in order to create the image I want"). It is art after all. The related blog is here.
On social software visualization, if activities, or attention, are tracked as locations (again, perhaps manipulated to get the desired result) this method could be used to visualize social software activity. But not interaction like vizster.
