A fundamental application of electronics is transformation — from power supplies that transform AC to DC to microprocessors that transform binary code to text, graphics, and sound. While transformations at many levels may be critical to the function of a device or application, it’s the high-level sensory transformations that hold the greatest potential to change the world. I’m talking about the high-level transformation of sensory experiences, illustrated at one level by Craig Lindley’s article on a digital color organ in this issue.
