Hi bemfarmer,

> There is also a different design with 4 leaves

Yes, indeed :-) I believe that was done by LOBOCNC (Jeff Kerr) you can search him on youtube but he claims his design is forked from Emmett Lalish's design (who made a five-leaf iris-dome box)

> A node with all leaves moving together might be possible?

I think it is!
