Gerry, why don't you simply use video? You go do the forms, videorecording them from 2 or maybe 3 different angles to capture all the various things you want to convey... while you are talking your way through it, then edit it down to a concise thing and you're done.
Then, upload it to your youtube channel (blocking comments to avoid the necessity of dealing with nonsense), and bam, done. Then, the student could just pull it up on their phone and watch/listen. Handled. No more worrying about the matrix theory of having an absolute reference direction combined with a changing relative reference direction based on opponents who move.... you'll be able to demonstrate it, and the students would be able to watch it.
