My coauthor at the conference last weekend said to me that our PowerPoint was "low-tech"; I countered that most hi-tech PPs are about as useful as, um, mammaries on male bovine. One person kept using a spin transition that, given the early hour and lack of sleep, was vertigo-inducing. Ours was on white background and does no fancy stuff, and I never did like the charts, but it was better than most anyone else's.

I am putting up today my poster by Edward Tufte, who has just posted a chapter to a new book called "Beautiful Evidence". As Craig Newmark notes, it's very instructive unless you're the poor schlub whose book he's skewered.
