(The jigsaw is made up of made up of a montage of photos of the Queen's Diamond Jubilee, it took him 35 days to cut the pieces, and he spent over 100 hours assembling it, but just a day after putting the final piece in place, his 150-square-foot masterpiece suddenly crumpled to the floor, breaking into thousands of pieces. And the moment is now a piece of YouTube history.
Never mind Dave - think of all the fun you'll have putting it all back together again.)
