As a kid who was left alone with a computer for way too long back in the early 90s, I remember learning English from Civilopedia and playing around with Borland turbo pascal 7. TP manual had an example where they built polynomials using linked lists. That was the first time I realized that you could store pointers to other regions of memory which store pointers. Nobody around me had any clue why I was so happy.
