Vertical slats for the staircase

Vertical slats to let the light come down the stairwell from the skylight and south facing window on the top floor.

I want the vertical slats going to the floor or the ceiling. So like this for at the bottom:

&

vertical wooden wall 08

The top / cap to the vertical slats to be capped with a hand rail, as shown below:

The slats give a continually different view / aspect.
