At my college there was a tiny tucked away lab that had these giant old dot matrix printers that were very very fast and noisy (they were under plexiglass covers). I don’t remember why I was in there or what I was doing but I must have sent a binary to them because they took off and were printing the winding characters. The admins banned me after that. Heh by junior year there were a handful of labs on campus that when I walked in the gray beards (probably grad students) just pointed at the door and I walked right back out.
