Just noting that these are all "scenes" and I leave it to you @zee-em to re-conceptualize them with new characters and I can adjust the text to match.  ...

The examples are a mish-mosh of different background colors and shape colors. I'll use this thread to track a convention for * background color * shape outline color * shape...

I wonder if just labeling it as "the desired vector" will be more clear than "this is what we want our vector to look like"? Also, technically the math is...

@zee-em small thing but I think the 3 on the right side of this figure should be position down where the line of 3 dashes is
