A merchandising tie-in for Very slow death.
Take a 1mm slice through the length of a smokers lung, and the same from a healthy one.
Take a hi-res image of each, laying on a lightbox, then pair them up in Photoshop, to look like a pair of lungs laid out in the classic view.
Create a repeat pattern wallpaper with the image.
Sell the rolls in the galleries giftshop.
