Today I managed to focus on writing and finally finished the 50-examples section on Conway's Game of Life. Then I looked at the list of possible topics in the TODO file and picked random number generation as the next topic I'll write about.
I had some extra time before going to bed, so I also fired up Inkscape and drew my very first diagram, an example Life board. Including the resulting SVG image in the Sphinx document was very easy:
.. figure:: illustrations/life-example.svg :alt: Example of a Life board. Example of a Life board. Cell **x**'s eight neighbours are numbered.
