If you put in 9 points of attachment in the rooms, one above and one below, one to the right and left, and then one in each corner top and bottom (not corner, but mid room) you could allow for more positions. Hands above and together or apart with feet together or apart. I did try hanging from the single point in the ceiling with multiple ropes, but when you do the ankles, the ankles take over, be cool if it was more of a horizontal suspension instead of vertical, or maybe you could choose. Nipple clamps I would think would be easy to add. Braided hair that is braided into rope for an attachment. Sliver chains could be another style. And, wrists and ankle cuffs (metal or leather). And definitely a body harness with side attachments. I know all that is a lot of work. You have done a great job so far.
