I was recruited for one of the first engineering positions at Tableau a very long time ago, but I turned it down as it just wasn't interesting enough. I think I was targetted in part because I was a SIGGRAPH presenter/author as one of the co-founders, Pat Hanrahan, was big into SIGGRAPH. Oh well.
It is a great success for a brilliant computer graphics professor: https://graphics.stanford.edu/~hanrahan/ http://www.graphics.stanford.edu/projects//polaris/
