Here you go:
Risso's Stairs
Step One:
First decide on the layout of the stairs. Here I've used blue tiles to indicate where I will be placing normal steps. Note there must always be a 2 tile space between the first and second step.
Step Two:
Place the first steps at either end, using teleporters to cut the stairs as you would with a spiral staircase.
Step Three:
Place a set of stairs at each end going crossways to the first sets (either the first or second tile along, depending on the height of your next step)
Step Four:
Place the next step at either end - note you may have to cut the stairs one at a time, as there is not enough room in the middle 3 tiles to place all of the necessary teleporters. Afterwards, delete the steps going crossways to delete the bottom of the stairs.
Step Five:
Place the teleporters to cut the 'flat' part of the bridge to the south or whichever way you would like the flat part of the wall to be facing, then place the stairs and cut to the desired height.
Step Six:
Repeat the above step for any remaining flat sections.
Step Seven:
Commit the design, then stand on the 'flat' part of the bridge. Use a square goza and target yourself so that it is placed at your feet, then raise it however high you would like.
Step Eight:
Stand back and admire your handiwork
