Jack-Oh!

A giant 275 foot jack-o-lantern smiles on the side of WaMu Center in downtown Seattle on Tuesday, Oct 30, 2007. To create the jack-o-lantern, building engineers studied the elevation of the building and drafted a plan to determine which blinds to close in order to create the image. The projection takes up 24 stories.
