An amazing hunt! As a chess lover, I really liked this. However, there is one detail that did not convince me and I will clarify it in my opinion:
This definitely makes the game easier to transport and store, as well as fulfilling its purpose: you won't lose the pieces of a board anymore; but if you do lose "magnetic wand" (which is also possible) then wouldn't you be in the same situation as if you lost a piece of an ordinary board?
Thanks for share this hunt!
