A spinnable ball, somewhat similar in concept to upturned mouse.
The first video game about Trackball was released in 1973.
Atari has published all these games
Requires no special support from the games or even operating systems themselves, as long as they support mouse-like devices, trackballs will function as expected. This is simply because (any sanely designed) trackballs will send proper movement data and not something you'd get from upside-down mouse.
