The video game Watch_Dogs views Chicago as a city where everyone and everything is linked through a central network — like something out of a sci-fi film. But to tie in with the games, the developers have made real versions that pull together mountains of data about Paris, Berlin and London — and the effect is chilling.
It's helped along by moody visuals, atmospheric music and interesting sound effects, sure. But that doesn't stop the real-time visualisation of everything — from underground trains, through electromagnetic fields and traffic lights, to social media updates — any less interesting or creepy. Go explore one of the cities — it's really quite compelling. [Watch_Dogs via Flowing Data]
