Chris Baker sez: "Brandon Sheffield, editor in chief of Game Developer magazine and creator of site InsertCredit, dug around in the Google patent archives and found some cool old patents by game companies like Nintendo and Sony. My faves are Sega's pimp VR headset (circa 1992, shown above) and a crazy racing game with a toy car that you mount in front of your TV."
