If you grew up in the era before, during, and after personal home computers then you might have a sense of that feeling of a before and after, where before there was nothing with a computer feeling to it, and then after (like, after you laboriously typed the BASIC listing in from a magazine article) there was something. Watching the something, especially if it had any rudimentary animation with crappy low rez character graphics, could really give one a strong emotive sense of the start contrast between the before and after. Even though the after was lame, the fact that it existed at all was amazing to behold and ponder and weigh.
