No - I've done a number of FP projects, but certainly spent less time with it than imperative languages. Here are some FP projects I've done --

    * Compiler for a scheme-like language in Haskell
    * simple webapp in Haskell using Yesod
    * small 2d game in Clojure
    * racket-based little language that compiles to openscad
    * lots of academic programming-languages projects in Racket
      (garbage collector, type checker, prolog, etc)
