How do scientific visual images which are not generally considered fine art (DNA trees, crystal diagrams, sonar charts) sometimes acquire aesthetic value outside of their specific scientific community?  In particular,  what happens when online scientific information changes into fine art? What are the economic, political and aesthetic forces behind such a change? When does this redefinition occur? What are the distinctive components of art and information in this case? What is the history of informational images acquiring aesthetic value?
