Thank you for the explanation! I really appreciate it.
And thank you for pointing the website out for me. It looks like it's still not fully functional yet, so I hope I'll be able to see more from them in the future. In the meantime, I think it's a great idea to have an "opening sequence" in mind when designing a puzzle box. The unorthodox placement of the numbers probably helps to hint at the owner how to open this puzzle. A great design!
Sorry for the late reply! But thanks a million for letting me know. I don't have a Facebook account, though. So I guess I'll have to follow him on his website instead. I would love to see how the final box turned out!
