K'nex Hoberman Sphere Expanding Ball

So, I saw my daughter's plastic expanding ball (Hoberman Sphere) and pondered if I cold make one.
I gave it a crack over a few nights, 2484 pieces, and when i had build one half it looked promising. However.... see video.  It seems the twisting of the joints was impractical to manage.
