Here's an idea that would save Nissan untold millions in marketing money and produce the same effect. Go to GoDaddy.com and buy the domain name "nissangtrvideos.com" (it's available, we checked), then pay a 17-year-old kid who has never heard the term "flash animation" about $500 (or a Playstation 3) to design a website that displays YouTube videos of the Nissan GT-R driving around the Nurburgring with that silly mask on. Seriously, it's traffic gold. Trust us.
One last thing, Nissan. If you think it's necessary to include a disclaimer that says "BLACK-MASK has no relationship whatsoever with terrorism, violence, unlawful activities or religious affiliations," then perhaps you should rethink your viral strategy.
Thanks to all who sent tips.
