In corporate and government bureaucracies, the standard method for making a presentation is to talk about a list of points organized onto slides projected up on the wall. For many years, overhead projectors lit up transparencies, and slide projectors showed high-resolution 35mm slides. Now "slideware" computer programs for presentations are nearly everywhere. Early in the 21st century, several hundred million copies of Microsoft PowerPoint were turning out trillions of slides each year.
Alas, slideware often reduces the analytical quality of presentations. In particular, the popular PowerPoint templates (ready-made designs) usually weaken verbal and spatial reasoning, and almost always corrupt statistical analysis. What is the problem with PowerPoint? And how can we improve our presentations?
Brian Eno is well-represented in iOS. His other apps like Bloom, Trope and Air invite listeners to touch the screen to make their own composition. Reflection ($30.99) is different, there is no interaction for the listener. The interface has three buttons: a pause button, a sleep timer, and AirPlay. Reflection produces endless permutations of Eno’s 2017 album, an hour and five minute long title track.
“Just calling it an app is akin to saying Falling Water is just a building,” writes one app store reviewer. “I would not call this an app,” agrees another, “Between the music and visuals it’s more like sonic architecture.” The visuals consist of slowly morphing rectangles that only seem to change in the split second you look away from the screen.
