Lol, that's a great story; if only that sort of thing was practical, how much more fun life would be :-) I actually had the opportunity to do something similar not too long ago. I'm a beginner learning to program and I had a little puzzle that I got from my grandma ~15 years ago. You have a tower of blocks with symbols on them, and have to arrange the blocks so that all of the symbols on each side are distinct [1]. The problem was small enough that I could just model each symbol as a prime and check uniqueness by seeing of the product was equal to 2 * 3 * 5 * 7 * 11 * 13.
