We've been obsessed with fun this week. Ogling the most amazing and groundbreaking playgrounds we've ever seen, playing with great new videogame technology, learning about a Teutonic revolution in board games, and wasting time with the PopSci Flash Arcade (curated by our friends at Kill Screen). And this week's Baarbarian illustration wraps it all up so nicely.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
