Description of phases:

1. The MVP blog post. Images can be screenshots, animation clips have been extracted (if necessary), and the transcript is formatted into readable paragraphs. There just has to be something portable to a website allowing someone to scroll through and learn the lesson.
2. 3+ comprehension questions have been added to the article.
3. Images have been vectorized, and the page could theoretically be turned into a pdf.

Lesson authoring peer review checklist:

• Includes authorship line: Text adaptation by [Name]
• The lesson has an informative/compelling description, fit for a preview on the home page.
• The lesson has no grammar/spelling errors
• The lesson has no mathematical errors
• The table of contents effectively conveys the overall structure of the lesson
• The lesson uses no # Top Level headings
• The lesson includes well-chosen comprehension questions
• The lesson incorporates the core visuals from the video
• The visuals are clear and helpful for understanding
• The components are used in the places and ways they are intended (see the readme)

High-level notes:

• The moving camera in 3D scenes makes the before and after comparison of a transformation tricky.
• What is the priority of interactive vs. animation vs. textbook output (printable)?
• Light/dark theming
• Does it make sense to leave the original grid from a transformation in place when transformations are introduced, but then drop the convention later in the series?
