Process: 

First I researched satisfying machine references online and designed a layout that is simple yet interesting.  

Then I modeled everything in Cinema 4D using splines and primitive shapes. 

Once I finished modeling the slide and other machine components, I began to animate the ball moving along the floor, slide and the tubes by using a cloner and animating the direction of the balls. 

After animating I then began texturing it in physical and using different area lights to brighten up the composition.
