OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

# Download all files from a given online directory
# into the a local directory without mirroring the 
# folder structure
wget -A <accepted only extensions> -r -l <levels of depth> -nd http://domain.com/folder/

wget -R <all except X> -r -l <levels of depth> -n http://domain.com/folder

A is 100 dimensional vector containing integers N between [1 and 10] (inclusive) distributed at intervals of 10:
i.e. 
at index x -> N
at index 1 -> 1
at index 11 -> 2
at index 21 -> 3

Problem:
-----------
Need to recode A into a 10x100 (Rows x Columns) matrix such that each column is a 10 dimensional vector y with y(x) = 1 the rest is 0
