The London School of Economics is launching a screensaver that will change daily in parallel with fluctuating financial data. "The Lost Horizon" is a fantasy mountain landscape that represents FTSE activity over the previous five days: its summits are peak trading points and its troughs correspond to low-activity trading points. The screensaver was created by artists-in-residence Matthew Cornford, a lecturer at Wolverhampton University, and David Cross, who lectures at the London Institute. Mr Cross said: "The everyday language and imagery of business is rich with metaphoric references to mountain landscapes. The concepts of risk and security in commerce are often visualised in images of climbers scaling the heights of an unspoilt wilderness."
