I'll level with you, I haven't got the first clue what's going on in these pictures.

It looks like a guy I used to hate at school walking around with the contents of Tanya Mackintosh's rucksack in a trolley.

I'm sure it will explain itself in some way when the show starts in Easter and be based around repairing the Tardis or something. A bit like like the A Team in a tweed jacket.
