In two years using Python, I never once searched for "Python X" without finding PyX, someone's labor of love making X easy to understand and use. Many examples come to mind. That's what hooked me when I started out: any tool I wanted was at my fingertips in 5 minutes, and just worked.
Optical character recognition was just about the only exception. So, I got excited when Google released Tesseract OCR, a straightforward, relatively accurate OCR package written in C++. Tesseract didn't have Python bindings, but it didn't take much work with PIL and subprocess to make it act like it did.
>>> from pytesser import *
>>> image = Image.open('fnord.tif') # Open image object using PIL
>>> print image_to_string(image) # Run tesseract executable on image
>>> print image_file_to_string('fnord.tif')
