implementation of BoxyLady2 aimed at pypy

README.md

To get pypy installed:

• curl -O https://bitbucket.org/pypy/pypy/downloads/pypy-2.0.1-osx64.tar.bz2
• tar -xvf pypy-2.0.1-osx64.bz2
• cd ./pypy-2.0.1/bin
• curl -O http://python-distribute.org/distribute_setup.py
• curl -O https://raw.github.com/pypa/pip/master/contrib/get-pip.py
• ./pypy distribute_setup.py
• ./pypy get-pip.py
• export PIP_REQUIRE_VIRTUALENV=false; ./pypy get-pip.py
• ./pip install hg+https://pyglet.googlecode.com/hg/
• ./pip install git+https://github.com/nodebox/nodebox-opengl
• replace sys.getrefcount in nodebox/graphics/context.py to work with pypy

try:
      from sys import getrefcount
  except ImportError: #pypy
      import gc
      getrefcount = lambda x: len(gc.get_referrers(x)) - 1
