In pictures: LG PenTouch PZ850T plasma TV

If there's one television accessory we never thought we would be writing about, it would be a chunky touch pen for a TV.

It's a gadget that doesn't really have a place in the TV world, but LG has decided to go ahead with creating it anyway - showing it off at IFA 2011 - and it looks like the company has had great fun in doing in.
