Dot-to-dot calendars

Here is an ingenious treat for the dot-to-dot enthusiast in your life, but only if they display great patience: the Dot to Dot calendar. Each day of the month is a dot, and if you join them together, by the end of the month you have a picture suitable for the season - thus, the December image is a reindeer.

It sounds like fun, but tortuously slow fun for a certain type of child. I mean, if they are the kind of person who can't let an advent calendar window go unopened before it ought to be, perhaps it's not for them.
