Andreas Sebring builds a limited run of these beauties every year. There is a waiting list which you can join by contacting him.
This is what Tom Stone writes about Quantum Logic on his homepage wargmagic.com
"In the May 2014 issue of Genii, as an intellectual excersise, Tom published “Quantum Logic” – a pastiche on Jim Steinmeyer’s work. That is, an imitiation of the style and taste of another creator. But after putting it in print, Tom looked at it and thought “Damn, this is really good! I want to perform that myself!”, and commissioned Andreas Sebring at Metalwriting to build the props. “Quantum Logic” is now the centre piece of Tom’s stage work. Andreas makes a small number of sets annually, and you can contact him and ask to be placed on a waiting list."
