Digital Slide Whistle was inspired by the Al Franken Show. This software allows users to create audio and musical representations of a single-variable time series (in other words, AUDIO CHARTS!). Includes (slightly outdated) files for Fox and CBS News George W. Bush approval ratings as well as Enron stock prices. This software is still in super pre-release stage, but it's pretty darn easy to figure out how to add your own time series!
