A strange computer programming course

I dreamed that I was taking some computer programming course where, in the classroom, I had to develop some real-world robotic mimicry system like: I draw and, as I draw, it stitches thread so as to reproduce the lines I'm drawing. We had a reasonable amount of time for completing the task because the class was a double-period, at the start of the day.

The dream transitioned to a different activity that I now forget more, where I was facing a related programming assignment but outdoors: I was approaching a small, ruined outbuilding where I was to perform some part of the task, not able to take long because some rather autonomous thing was out there pursuing me.
