Algodoo

Instructions:
1.Drag the throttle lever to the left.
2.Drag the flywheel brake/ignition switch to RUN position.
3.Press and hold [.] key (period) to activate the starter.
4.Release [.] key (period) as soon as balls are spawned inside the cylinder
5.The throttle can now be adjusted to attain a specific rotational speed

Parts:
Left Gauge/Slider: Flywheel Brake and Ignition Switch Control
Center Gauge/Slider: Throttle Control
Right Gauge/Slider: Tachometer
Yellow Levers and Spring: Flywheel Brake
Bright Blue Levers, Spring and Gear: Starter (use the [.] key (period) to activate it)
Dark Blue Disc and Gear, Along with Gray Disc: Flywheel and Crankshaft
Orange Circles (near the flywheel brake) and Small Box: Ignition Switch and Ball Spawner
Green Piston: Power Piston
Red Piston: Deleter Piston (clears balls out of cylinder)

Mechanisms:
Ball spawning is done on piston contact with the small orange box in the cylinder.
The ball is then deleted by the red piston at a 90 degree offset from the power piston.
The ignition switch changes the collision set of the orange spawner box.
Throttle control is achieved by making the balls larger or smaller based on the angle of the throttle lever.
The tachometer uses a frictional gear system.
