You can make your own glasses for this effect using an old pair of sunglasses. Simply knock out one of the lenses so that only one eye is viewing through a darkened filter. (Gray is better than the amber colored lenses.) This effect works on images that move laterally across the screen, and is effective (to varying degrees) with any action scenes, whether intended to be 3D or not. For example, try watching a football game or car race.
It does matter which direction the action is in and which eye is covered, but I'm not sure of the specifics. I think if the action is left to right then the left eye should be filtered. When a production company is planning a 3D sequence they stage action in a particular direction to complement the glasses which will be distributed for the event, and to make sure that the foreground/background effect is as intended. For example, that objects moving left to right are in the foreground, and those moving right to left are in the background. I'm not sure if they also use any other special camera filters or effects for the process.
Several shows, commercials and events were done using this cheap faux 3D technique. The upside of this process is that the program content looks normal to viewers who do not have the glasses.
