Here is the script that shows the Penrose dot matrix python. Yes, this is a valid Phython code that can be run.
Penrose lattice, physics terminology. In the 70 's, British mathematician Penrose first proposed this concept, called Penrose lattice (pen-rose tiles).

When this program runs, it outputs a 1000x1000 image file containing about 2,212 Penrose dots rendered by 3D stereoscopic effects. Here is a part of the image (click to enlarge).
Running the script requires Pycairo. It's only in Python and it's a standard Python script, but I'm trying to make it more concise, so I cut it out a little bit.
Note: Pycairo is a set of Python versions of the Cario graphics library.
The Penrose lattice is cool because they cover the entire plane in a non-cyclical way-the converted copy of the picture never coincides with the prototype. They were invented by a series of attempts by Mr. Roger Penrose to tile the plane of the Pentagon.
Python is not a confusing programming language compared to C or Perl. This kind of comparison never seems to happen, and there are not many puzzling examples of Python on the Web: You can find some examples in the official Python FAQs or on various pages like here and here. In 2011, Pycon also had a panel discussion on this.
I believe that outputting a high-resolution image is the first confusing Python program. If you know other examples, you can tell me in the comments.
