I’ve been curious for a while what it would take to create lesson style screen recordings, and finally got around to trying one myself:
This is an introduction to Geometric (Clifford) algebra. I briefly outline a geometrical interpretation of various products of unit vectors, rules for reducing products of unit vectors, and the axioms that justify those rules.
I made this recording using the OBS screen recorder, using a Mac, drawing with a Wacom tablet and using Mischief as my drawing application. I have to find a way to do the screen clearing transitions more smoothly, as there are sizable dead time delays while I do the ‘File -> Import -> Recent -> … ; Don’t save’ sequence in mischief to reload. I also um and ah more than I like, something I think I could avoid if presenting this to a real live person.
