I must say that this technology is amazing. I was in Athens in late December, and tried them in person.
The themes are made in such a way, that the cuts are minimised. This means that any picture or photo
embedded on those cubes looks very impressive and complete. Friction does not seem to affect those
themes because of their good precision, but as we all know, time will tell more about it.
In my opinion, an excellent improvement on the look of nxnxn puzzles.
