Mass:werk’s Error Pages Feature Playable Versions of ‘Space Invaders’
Vienna, Austria-based designer and developer Norbert Landsteiner, owner of mass:werk media environments, has created a series of custom error pages for his website that feature a playable version of Space Invaders. You can control the game and also control what error code is displayed in the center. I was able to pull up the WTF error code (seen below) by typing in “000.”
