From there, I'd hit Luis Bunuel's Un Chain Andalou, which is really bizarre also but excellent. Plus, if you like surrealism, Bunuel's later films are a goldmine.

Edit: Oh, and also, for that sort of high-contrast grainy cinematography, Aronofsky'so Pi is grade-a, plus it's got that guy from Breaking Bad:
