I recently watched the UK Channel 4 documentary '[Inside LEGO At Christmas][1]' and in it, one of the employees of [Bright Bricks][2] 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][3] 

 - 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.
