Ever wondered how controllers transformed from arcade joysticks and knobs to the sophisticated input devices we take for granted? This comprehensive evolution of video game controllers print from Pop Chart Labs outlines everything, from old-school unknowns like Nintendo's ColorTVGame 6 and the Sega Light Phaser to the Ouya and PS4's fourth dual shock iteration. 
 
Even cooler, it shows how designs influenced each other, giving some perspective on why both the NES and the Sega Master System Famicom controller resemble the Famicom. (The spare design is pretty slick, too.)
 
The 27"x39" print will run you $36.
