Waiting for Guffman, Kontroll, Scanner Darkly, Slacker, SLC Punk!, The Gods Must be Crazy, Go, and Adaptation. That should give you a good start.
Edit: I hadn't noticed that you wanted only recent, but the films I recommended are all good and I'd still like to suggest them.
Black Swan, Greenberg, Fantastic Mr. Fox, and Inglourious Basterds.
