Shaker: http://bigpharma.gamepedia.com/Shaker
This thing doesnt shake drugs, it shakes purple balls...
It is fully automatic, it uses springs with variables to create the movement
(negative damping for the shaking for ex.).Also, the balls loop, so you needn't copy anything.

Have Fun!

For the ones who care, the controlling unit is about 1 to 1.5m away from
the ball pipe on the right side, floating in the air.

Damn, 2 scenes this day, new record!
