What is the special LEGO Movie 1x1 element shown in the Channel 4 documentary 'Inside LEGO at Christmas'? I recently watched the UK Channel 4 documentary 'Inside LEGO At Christmas' and in it, one of the employees of Bright Bricks showed a tall 1x1 element that he described as a brick that Lego came up with for The Lego Movie set.

It can be viewed on YouTube here @7:17 


Is this element included in any commercially available sets?
Is it indexed on Bricklink?


I have done several web searches for other references and also searched Bricklink but have been unable to find any other information about it.
The Piece of Resistance


can be found in 11 sets
