Thanks! Yes, I guess so - when the pressure is low it becomes more slithering bag than rolling blob. Thanks for sharing these details about the workings of Gish - it's fascinating.

Did you ever look at using pressure on the segments instead of spokes around a central hub? I was playing around with this recently - it allows for more extreme deformations and inversion is never an issue because the pressure is always outwards

Ok, I think this one is topologically different. Highly distorted angles, but still all hexahedra, meeting face to face.

Ah, maybe it's actually just a distorted version of the same thing Keenan originally posted!

Not topologically- that top right face is triangular in shape, but topologically a quad.

If you don't care about angles, one option is like this:

Here's another way of showing it for N=3. View full size to see the grids

The squares of the tilted/scaled grid which contain N points of the unit grid are shaded (below a zoom in for N=11). Some combinations of angle/scale produce these interesting *almost* repeating patterns

Here the squares containing 11 points

The patterns that show up in imperfect solutions are quite fascinating - here's a scaled and rotated grid with all the squares containing 7 points from the lattice shaded

...and here's one where they all contain 5 Does a grid like this exist for 3? or 7?

Here's one where *most* of the squares contain 5 points of the lattice

I wonder about the case with not just a single square but a grid where each square contains N points of the lattice?

Perhaps it could be helpful if I add a new solver mode which iterates to a given precision of convergence before output (like ZombieSolver, but starting from last output iteration each time), and gives message when convergence cannot be reached.

I see - I would like to improve the way it handles hard constraints + make it easier to set up so they are enforced strictly at all stages of the movement + better feedback given when overconstrained. Accurate linkage simulation is already possible now with right setup though:

What error? I think Kangaroo works quite well for linkages already. I'm interested to hear about where you see the limitations.
