[cairo] The Qahirah Notebooks Project

[Lawrence D'Oliveiro]

I thought it might be fun to create some IPython notebooks to illustrate
various Cairo graphics concepts. IPython supports embedding Latex
mathematical markup, so you can put together nice-looking formulas
showing matrix manipulations and the like. And not only can you
generate your own graphics, but you can add interactive sliders and
other widgets, letting the user bring those graphics to life.

So here is the current collection of Qahirah notebooks:
<https://github.com/ldo/qahirah_notebooks>. I have done one on cubic
Bézier curves, and another on matrices.
