No. Those are combinations for an entire cube, but it's just one side.
6^9 = 10,077,696 codes.
Still too much. 2x2:
6^4 = 1,296 combinations. Probably too much, so we could divide it by 4 possible rotations to get 324 combinations, not bad. But how would we know which rotation to hold it at?
The problem is the outside... those three squares can't be more or less squares. We could have a handy little frame to hold on the outside before scanning. This way it is always three!
I would love to see one of these cubes and I sure would buy one
But one question Would you need to make a app to hold all the info for the QR codes and to scan them?
