Thingamabobs and "watchamacallits" take center stage in GARY GADGET BUILDING CARS, a game from Viva-Media that encourages children to experiment with old auto parts and other junk items to build cars. Kids work with Gary Gadget, an inventor who owns a salvage yard that provides over 120 parts. By trial and error, you learn that a car must have an engine, battery, fuel tank, gearbox, brakes, horn, steering wheel, and tires (or something just as good). Once you have assembled a car with all the necessary parts, Gary invites you to take it for a spin and visit Gary's neighbors -- leading to 16 different missions.
Kids scavenge the yard and select pieces to click-and-drag into Gary's workshop. Gary provides a frame onto which the parts will adhere. To find out what a part does, you need only click on it, and Gary will speak up. If you drag a part close enough to where it can fit on the car, it will click into place.
