A to-be-animated creature is set up by creating a rig, defining connection points on the rig, and associating geometry with the rig via the connection points. Each of the pans preferably includes a pair of rotary discs thereon, with all of the discs of the system rotating simultaneously and unidirectionally to convey material along the conveyor run. A pump housing flapper valve on the intake end of the pump housing can be selectively open or closed by a control rod mechanism to facilitate a flow of water by direct drainage through the pump housing and the tile into the ditch, or for pumping water through the impeller housing, the pump housing and the tile when the water in the ditch is at a higher level than the water in the field. This is achieved irrespective of in which one of the directions of lines the tip of the blade faces, the lines being obtained by extending the generating line of the grinding surface from both ends of the generating line. If the requested connection is a first connection opened by the software application, then the software application is associated with the requested connection in the connection control information. Tie down members extend from the tow rack frame to the motorcycle frame.
