The great thing about spec work is

it doesn't have to be approved.

Like this campaign for Clue board games. Found this on trendhunter.com and while it didn't state if this was produced or not, I'm going to guess NOT.

From Trendhunter:

Created by Jenny Luong and Jared Friedberg at Humber College in Toronto, Canada the campaign places special liquid soap dispensers that contain blood-red colored soap in public washrooms. When you try to wash your hands, the soap creates the realistic illusion of you washing the blood off your hands.

Pretty cool idea, but I'm not sure how the average consumer would react to inadvertently dousing their hands in blood-like soap, courtesy of a board game.

I also think it would hear a resounding chorus of crickets if they presented it to the suits and ties at Hasbro.

But, it never hurts to keep thinking. Always.
