The Knot 4kids

You know how much I like your kids series This one is another step in children's mind as they have to untie the headache, not just find the path. For those with a conceptual view it could be a pleasure but it will be definitely unusual and challenging for them. Thanks a lot!

Again, I would want one for grownups. ...Or perhaps older kids. Think of it as a 3D sliding puzzle (which seems to be all the rage this week).
