A machine adapted to produce on a screen images of a road and motor vehicles, not under the control of an operator of the machine, which run over the road while changing lanes thereover. An illusion of motor vehicles changing lanes while running over the road can be created by the relative movement of a road image forming means represented on a rotary disk and motor vehicle models supported by a rotary body, such relative movement taking place across the width of the road forming means.

An obstacle avoidance driving type toy has a housing with a motor located in the housing. The output of the motor is fed to a switch member which, in turn, conducts the output to either a first transfer mechanism or a second transfer mechanism. The first transfer mechanism transfers output of the motor to a moving member which includes an encounter sensor located on it. An object, under the control of the operator of the toy, is maneuvered with respect to the movement of the moving member, and if the maneuvering of the obstacle is not coordinated with the movement of the moving member, the obstacle will encounter the encounter sensor. When so encountered, a signal from the encounter sensor is fed to the switch member, which switches the output of the motor to the second transfer mechanism. This activates an indicating mechanism to indicate the encounter between the obstacle and the moving member, and additionally, sets a reset mechanism which then resets the switch member such that the output of the motor is once again transferred to the moving member.

An amusement device or toy which includes a vehicle, such as a toy motorcycle, attached by a tethering arm to a generally upright base support in the center of a game board. A path of travel for the vehicle is defined on the game board about the base support and a plurality of playing pieces or obstacles such as ramps, barrels, and tires are positionable on the game board in the defined path of travel to change the operating characteristics of the vehicle, as performing "stunts." A centrally disposed variable speed motor is provided to drive the vehicle and tethering arm about the game board. A deck of playing cards is provided which instruct the players of the game which playing pieces or obstacles are to be placed along the path of travel and successfully maneuver in order to obtain points.

A game and method of playing it to simulate a minimally invasive surgical procedure. The game comprises, a base member over which a transparent domed cover having a pair of openings is located. The cover defines a work space thereunder. The base member includes a graphic likeness of a being, e.g., a woman at the bottom of the work space. A plurality of anatomic parts shaped to simulate internal organs of the being are located in respective cavities at anatomically appropriate places on the graphic likeness. A lifting instrument simulating a conventional laparoscopic instrument is provided to be extended through one opening in the cover to grasp and lift the anatomic part out of its cavity without touching the cavity with the instrument, else a lamp on the base member is automatically illuminated and a buzzer sounds. An extraction instrument simulating another conventional laparoscopic instrument is provided to be extended through another opening in the cover to enable the lifted anatomic part to be transferred to the extraction instrument so that it can be taken out of the work space by the extraction instrument. Plural cards are provided to establish the surgical procedure to be attempted by each player. Play money is provided as a fee for each player who successfully completes a surgical procedure.
