Ever wanted to walk down the street and blast aliens? Well, that may not be possible outside the gaming context, but Parisian artist Space Invader is at least creating real targets. His site catalogues five years of 'invader' tagging, where he plants colorful mosaics of the original arcade aliens all over buildings, curbs, sidewalks, security cameras, and rooftops of major metropolitan areas. His documentation is extensive, ranging from detailed 'invasion' maps of Paris, Tokyo, and Perth, to shaky video of him hacking the Hollywood sign. This is more than merely a portfolio site, though. Invader's e-store lets visitors purchase their own DIY 'Invasion Kits' to spread the arcade mayhem in their own town. Bleep! Bleep! The Martians are coming! -Jonah Brucker-Cohen
