Theme change not yet complete, but looking good. It’s a widened version of Clemens Orth’s Relaxation_3column, itself a derivitive of John Wrana‘s two columned Relaxation theme. I found it on the WordPress Codex, and though it was among the first group I looked at, I dutifully clicked through to every other three-columned theme listed there.
Anyway, expect the banner to change, and I’m working on how I want to handle the width on smaller monitors (where “smaller” actually equals anything narrower than 1280px). Eh, life goes on.
