Looks great. How many of these 4D style puzzles do you intend to have/already have made?
Well, in graph theory, the possibilities are endless!
(which is why I call those designs as "Graphidrons")
As long as I do not run out of materials, I will always come up with new.
There are the regular ones which are more attractive and efficient.
Then there are other ones based on well known structures, etc etc etc.
But at the moment, I am first targeting the most symmetric graphs.
Remember, my Master's Degree was on Algebraic Graph Theory, so these
structures are very familiar to me.
Finally, be prepared for the revelation for some more puzzles, based on
higher symmetry than 4D!!!
