Copy-less bindings of C-generated arrays with Cython

Cython example of exposing C-computed arrays in Python without data copies

The goal of this example is to show how an existing C codebase for numerical computing (here c_code.c) can be wrapped in Cython to be exposed in Python.

The meat of the example is that the data is allocated in C, but exposed in Python without a copy using the PyArray_SimpleNewFromData numpy

Convert videos to proper formats for HTML5 video on Linux shell using ffmpeg. Will probably convert this to a bash script later, but for the time being, here's some examples. Not sure there have actually sensible dimensions and bitrates for web video.
# webm
ffmpeg -i IN -f webm -vcodec libvpx -acodec libvorbis -ab 128000 -crf 22 -s 640x360 OUT.webm

ffmpeg -i IN -acodec aac -strict experimental -ac 2 -ab 128k -vcodec libx264 -vpre slow -f mp4 -crf 22 -s 640x360 OUT.mp4
# ogg (if you want to support older Firefox)

Seesaw REPL Tutorial
; A REPL-based, annotated Seesaw tutorial
; Please visit https://github.com/daveray/seesaw for more info
;
; This is a very basic intro to Seesaw, a Clojure UI toolkit. It covers
; Seesaw's basic features and philosophy, but only scratches the surface
; of what's available. It only assumes knowledge of Clojure. No Swing or
; Java experience is needed.
;
; This material was first presented in a talk at @CraftsmanGuild in
; Ann Arbor, MI.
