Since 2006 we have been writing “annual reports” of our progress as an organization. Essentially, they are christmas letters, but we had the idea to write them in the style of a business just for fun, and have mostly stuck to that theme. Also, that way we don’t feel pressure to actually finish the report before Christmas, but rather usually around the turn of the year. I have been making them with LaTeX the whole time, for both pdf and html versions, and we always include a graphic. We have a good time making them.
