Lesson clips

Each one opens to the clip filling the screen — no sidebar, no comments, no suggested videos. Press Close or Esc to come back.

Nothing on the YouTube player can be tapped. YouTube puts its own buttons along the top and bottom of the picture — a channel link, “More videos”, “Watch on YouTube”. Those strips are covered here, so a stray tap cannot leave the clip. Tap the middle to pause or play, Full screen to fill the projector. Close or Esc ends it.

Nothing here is stored or sent. The filmed clip is linked, not copied. The drawn clip was made for this lesson.
