Numberjacks
Numberjacks is a British children's television series that originally aired on BBC2 in the UK between October 2006 and 2009; re-runs of the episodes are still shown regularly on CBeebies (when it was on BBC2, it was only on occasionally, and when it first appeared, it was only on for a week). It was produced by Open Mind Productions for the BBC and features a mixture of computer-generated animation and live-action.
