This reminds me of something that's been bugging me about HP's ad campaign that features silhouettes of hands with writing on them. They remind me an awful lot of the cover of Jonathan Safran Foer's novel, 'Extremely Loud & Incredibly Close.' A little research has turned up that the cover of JSF's novel was designed by Gray318 (a.k.a. Jonathan Gray), a Londoner who designs book covers for US and UK publishers. The only commonality that I can find between Gray and HP is that Gray may be "developing a full digital typeface based on these letters, which is to be licensed exclusively by Hewlett Packard." (mentioned here, which references mad.co.uk -- but you can't read the article without a subscription ... which I don't have.)
