My SAS and SPSS are rusty as well, so things may have changed, but I think it is still difficult to do simulations and general bootstrap type analyses (simulate or resample a dataset, analyze it and capture a piece (or pieces) of the output, repeate many times and end up with a vector/matrix of interest).
Some aspects of graphics, adding to graphs I believe is still quite a bit easier in R/S-PLUS. Show some interactive graphics, start with simple things like the identify function, up to more complex examples (some in the TeachingDemos package as well as other places), also look at the iplots and rgl packages. I (and I expect others here) am interested in what you find, maybe you could post a link to your finished presentation after you give it. Those are the things that come to my mind first, hope it helps, -- Gregory (Greg) L.
