void corners

not on every level the same corners are the shared spaces,
on the snake chain, the idea was to have one end as shared space and the other corner as void. here, by rotation this rule is applied to different corners.

the void can make space for a slightly larger shared space between different levels.

the void can make space for a slightly larger shared space between different levels.
making the shift of levels a little more extreme can be an option too, right now the shift is 2.5m's on every level.
