I was first introduced to computers like most Xennials in grade school by something called “Logo Writer“. This was probably around grade school along 3rd or 4th grade. This program allowed the user to move a turtle graphic around the screen that could output a vector line with basic input commands. It was a like a HUGE deal back then as PCs were not quite yet in the home and programs like this were not in every school system. Can vaguely remember the teacher also having a physical turtle robot about the height of a child’s chair that you could sync with the computer via a ribbon cable so the commands carried over to this device could make those same moves in real life.
