// Goodby Silverstein & Partners and Number 9 built a wicked web site claiming to be as tall as Mt.Kilimanjaro for a new celebrity and charity-infused Hewlett-Packard campaign, SUMMIT ON THE SUMMIT, here. The cause? global clean water. Climbers signing up to scale Kilimanjaro with HP notebooks include: Alexandra Cousteau (her grandfather is Jacques-Yves Cousteau!), Jessica Biel, Lupe Fiasco and Kenna. They’re using the HP notebooks to log their experiences through blogs, tweets, video and photographs. The interesting part is that the site matches their spot on the mountain. Sponsor a foot here.
