Project of the month
Project of the month is a variation on Project of the week. It was maintained by the same person, and is now no longer happening, unless somebody else wants to step up and maintain it.
Project of the month is less often than project of the week of course, so would require a bit less regular effort. A new project each month is probably a more realistic aim. The project wouldn't need to last for a whole month. It could be a short two day mapping sprint, with a new idea once-per-month.
But anyway... see Project of the week for more details
