Spring2011 was a lot of things, and one of those things was amazeballs, and that thing was due to Portal2, which was amazeballs, which is a thing you should already know.
And within this life-altering game (seriously my life was altered, what, just me?) among the billion things worth talking about, one tiny (rad) detail was the collection of retro workplace posters in the old ApertureScience offices.
Those are just a few, play the game, for realsies. But the other day I came across some actual retro posters FOR SCIENCE that were collected on brainpickings, and they were pretty darn rad too. Retro+cooldesign+science= and a good time was had by all.
