Another interesting "urban legend"-tier object from the computer era was the Polybius arcade machine, though it's more in the fictional section than fact.<br>I just love how even now in this age of the Internet and computers where any data can (relatively) easily be found with enough searching, that there is still room for speculation, urban legend, and incomplete information - it's very fun and kinda spooky in a way to just know that because of the data that's just been lost through time that we just don't have all the answers.<br>And this is coming from someone who has a legitimate fear of data being lost forever! I guess curiosity can still manage to override it.
