Machinima — a portmanteau of “machine” and “cinema” — refers to movies filmed inside video games. The art form had a renaissance in the 1990s, and many thought it had a future in Hollywood. Among the early pioneers were the New York animation collective the Ill Clan, who puppeteered characters in real-time inside the video game Quake, bypassing traditional animation rendering. This technique exploded i...

In this second episode of Hidden Levels, Amory traces the history of the humble-yet-genius joystick — from early 20th century aviation, to 1970s video game consoles like the Atari 2600, to the Nintendo 64 thumbstick in the 1990s, to what some consider the joystick's greatest implementation: the dual-thumbstick controller.
