French artist, Space Invader, or someone close to him, has posted pictures giving Flickr users an inside look of his ‘invasion’ of Vienna throughout June 2006. Creating a mixup of art installation and social exploration game, the artist created tile-based pixel art recreating characters from the classic video games Pac-Man and Space Invaders, then pasted them to buildings around Vienna, Austria. Space Invader is currently at residence in Vienna’s Museumsquartier.

I’m not 100% what the story behind these tunnels or the photos are (I’m trying to find out more information), but they appear to be some sort of flood control and/or irrigation and drainage tunnels. Whatever they are, these photos are extremely amazing and remind me of a mix between Blade Runner and Alien 4 movie sets. If anyone has more information on these, please e-mail us [Email address: nerds #AT# bunchofnerds.com - replace #AT# with @ ] and we’ll be happy to update the post.

[Update 1. Thanks to the many people emailing us regarding this story! More information is coming to light and I'm happy to update the post with what I've learned. The infrastructure is named the G-Cans Project and is an underground system in Tokyo intended to collect floodwater. I've also been forwarded an interesting travel diary of someone who was able to take a tour of the facility! Thanks Jackson and everyone else mailing me on this.]
