Don't miss the program he wrote after teaching himself BASIC from a book at age six (Fig 5 / book page 222 / PDF page 10):
> 320 print "(brmmmm-brmmmm-putt-putt-vraow-chatter-chatter bye mr. fibonacci!)"
> 320 print "(brmmmm-brmmmm-putt-putt-vraow-chatter-chatter bye mr. fibonacci!)"
I remember when I was 6 or 7 teaching myself Applesoft BASIC and writing programs with funny (to me) little print statements all through them - when computing was just exploding with possibility.
I wouldn't have had a clue what a Fibonacci sequence was though ;)
