The concept of each die having a story and carrying that memory with it greatly reminds me of a recurring theme in the movie, "With Honors." Joe Pesci's character has lived a hard but interesting life and when he's somewhere fondly memorable, he picks up a small stone to add to a collection. He says he can then hold each one and go back to that good memory when he wants to. The concept of an object having memorable significance is certainly not new to humanity, so why not a die? :)
