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?
I have appropriated from Brian Eno and others the distinction between architecture and gardening, and have described my blog as a kind of garden. But lately I’ve been revisiting the architecture/gardening distinction and I have come to think that there is something architectural about writing a blog, or can be – but not in the sense of a typical architectural project, which is designed in advanced and built to specifications. Rather, writing a blog over a period of years is something like building the Watts Towers.
Simon Rodi didn’t have a plan, didn’t even have a purpose: he just started building. His work was sustained and extended by bricolage, the acquisition and deployment of found objects – and not just any objects, but objects that the world had discarded as useless, as filth. You put something in here, then something else, you discover, fits there … over time you get something big and with a discernible shape. Not the regular shape envisioned in architectural drawings, but nevertheless something that can be pleasing or at least interesting to look at – an organic and irregular shape. A geometry of irregular forms.
