IdN is bimonthly creative magazine that is recognized internationally as the leading medium for digital content creators. With an amazing heat sensitive cover that reveals hidden images when touched, IdN Special Edition 04 focuses on interactive elements in graphic designs with a strong emphasis on music and sound. This is a fascinating collection of work crated recently for a selection of high profile international corporate clients. It discusses how interactive design has been pushing the boundaries of art and corporate communication over the past few years and demonstrates how the world's top digital designers are meeting the challenge this demanding discipline presents to the traditional design world. Up until publication of IDN Special Edition 04 the graphic interpretation of interactive elements had clearly lacked an auditory flavor.
