Just press play.
I was wondering how I could make what looked like a sine-wave, but being able to modify where it was, and how large/wide it was. That's how I came up with this code, which looks like a sine wave when played. Originally, I was planning for this to run without screen refresh, because I didn't want it to take half an hour to draw a line in my upcoming project. That's why the code is in a custom block.
