Building a Crystal Clear Whiteboard
<i>Everything he’s writing is backwards. That’s not actually a problem in this case as [Michael] uses flip teaching.</i><p>But flip teaching is nothing to do with writing backwards, or at least not according to the linked Wikipedia article.  So he is actually writing backwards?<p>Edit: Ah I see, <i>the whole scene</i> is mirrored, including him.  I guess that could work, although then diagrams really have to be drawn backwards (assuming western L->R convention), and any computer generated text will have to be projected backwards on the whiteboard.
