Here's a simple script that takes full advantage of 4chans API, it allows the simple viewing of threads and allows you easily download all of the images within a thread... Why would you want to do that? Because now you can...easily
The script is located here 4chan-tool.py. To view the help options use python 4chan-tool.py -h The output is also coloured in the terminal so you'll also be needing this handy terminal colouring library icolor.py
