Just wanted to point out a couple of very nice pieces of source code I came across recently.

ipin.py

Firstly check out this Python code ipin.py, by Axel E. Brzostowski, which converts png files from an iphone application into a format that you can read on any computer.

The python code is clean, easy to read, almost like literate programming. Very useful if you want to write a similar application that processes every file in a directory.

transmission

Another really nice program, is really a website. When you run transmission-daemon (linux bittorrent program), you can connect to it with a command line app called transmission-remote. In addition you can connect via a built in web server, which is a really excellently designed application. The html and javascript is so well documented and tidy it's as beautiful as the actual web page. Check it out here.
