I thought Grasshopper users out there might be interested in my use of Grasshopper in the Queen's Baton for the next Commonwealth Games in Glasgow, next year.

Grasshopper gets a very slight mention in this core77 article, but it was what I used to develop the signature lattice framework that you see in the design. 

Grasshopper wasn't used for the "puzzle mechanism" at the top of the baton, but the first concepts and prototypes for that were developed in Rhino.
