Fun with ctypes

This probably only works on Intel-based OS X machines:

>>> import ctypes
>>> print ctypes.c_char_p(
    -16 * 4096 + 0x1600
).value
Your karma check for today:
There once was was a user that whined
his existing OS was so blind,
he'd do better to pirate
an OS that ran great
but found his hardware declined.
Please don't steal Mac OS!
Really, that's way uncool.
