Scrolling Lights with a Sphere
It's very funny build !
Change the angle of the ramp to accelerate or decelerate the scrolling sequence !
Use a sphere creator and pressure switches : when the ball roll on the pressure sensor, it activated, blinking the attached light.
At the end of the sequence, the last pressure switch is connected to the sphere creator, producing a infinite loop
