The invention is an apparatus consisting of a set of parts that can be assembled into a variety of internal-combustion engine analogs. The set of parts comprises a set of platform parts that can be assembled into a platform having a platform rotary axis and a platform reference axis normal to the platform rotary axis and a set of driver parts that can be assembled with a set of platform parts into a driver assembly supported by the platform. The driver assembly comprises one or more drivers, each driver containing a first driver point and a second driver point. The first driver point travels back and forth along a driver line segment while the second driver point travels in a driver circle around a driver-assembly rotary axis.
