Last year I read a really awesome book written by Vilém Flusser.
He has books published in English, Portuguese and German. Unfortunately the one I read I only found in Portuguese.
Flusser describes a world fundamentally changed by the invention of the “technical image” and the mechanisms that support and define industrialized modern culture. He argues that whereas ideas were previously interpreted by written account, the invention of photography allows the creation of images (ideas) taken at face value as truth, not interpretation that can be endlessly replicated and spread worldwide.
Really worth reading, specially for those that work in the interactive/design/web industry!
