uk mobile network giffgaff are all about providing top notch refurbished phones and shiny gold goody bags that give their customers extra data.

we were faced with a triple challenge: get people to donate their old phones, using only ooh media, and show how giffgaff gives back.

we solved the problem with an unexpected solution:
giant golden toilets.

and it won us a pencil! not too shabby for a bunch of lavvies.
