My 12 year old son and his friend spent much of last weekend mixing and matching all his lego minifigs to make his own Dr Who Lego.
Given that there was nothing manufactured specifically for what they were trying to make, I think they did a great job.
I've never been that interested in branded Lego, but if they ever did a merchandising deal with the Beeb over this, they would have a large amount of my money. And plenty of my childrens' too.
Please excuse the poor photography. I rushed a bit, perhaps I can upload some new versions later.
