brainfucker is a Brainfuck interpreter written in Python. The interpreter itself was written in one sitting (about 3 hours, hence the lack of a long commit history); everything else (verbose mode, etc.) is just tweaks.
>>> import brainfucker
>>> bf = brainfucker.Brainfucker(useASCII=True)
>>> bf.interpret("++++++ [ > ++++++++++ < - ] +++++ .") # print 'A'
A
>>> bf.resetEnv()
>>> bf.useASCII = False
>>> #read two numbers and multiply them
... bf.interpret(",>,< [ > [ >+ >+ << -] >> [- << + >>] <<< -] >>.")
bf> 12345
bf> 2
24690
>>> bf.resetEnv()
>>> bf.verbose = True
>>> bf.interpret("++ [> ++ < -]")

[0, 4, 0, 0]standards for "nice" brainfuck - helped greatly with laying out the details
learn x in y minutes where x = brainfuck - short programs for testing the interpreter (shown in usage section)
- write unit tests
- optimize away long strings of
+and- - add a compiler (maybe?!)
