This is Quique, a boy born as a head. Now, after 27 years doctors say that he could be "assembled" into a body, so he's made this website to find himself a proper one. Please, be kind, help him out. Read the blog here: http://www.quiquethehead.com/
This campaign is made by Shackleton. Diesel appears two or three times on the site and is also the registrant for the domain name, and two of the tags of the video are "fashion" and "motorbike". Smart and funny viral/campaign, cudos to both Diesel and Shackleton!
