Ambient information visualization normally does not reside on the screen of a desktop computer, but exists in the general environment, in the periphery of the user's attention. The aim is not only to provide useful information, but also to blend in with the surroundings and to be appealing to the eye. In this paper we use ambient visualization to represent financial data. Financial visualization is the practice of making large financial datasets into images. In comparison to the bland financial data, the visualization is easier for people to understand, especially as the image changes. In this paper we describe a research project that uses different images of trees to represent the real-time changes in stock prices and volume.
