Or is it strictly each string operates the nearest corner?
Having it strapped to your back seems particularly complicated, but it's quite effective in making sure you don't simply lean forward!

Pushing down on the left raises the left, tilting forwards tilts the glass backwards etc. If you twist the handles a half-turn it means that tilting forward and backwards is no longer reversed at least. I guess you could also pass the handles over the top and that would fix the up and down too. I didn't think of that.
