I couldn't resist trying out Youtube. I had two short videos I made in the late 1990s that I put up. One is about a six sided mirror I made. The idea was to create
an object that reflected sound just the way a mirror reflects light.
The video is amateurish so please be tolerant of my poor video skills.
I've also thought about a gravity mirror but haven't done anything with
that image.
The second video is a short but real story told by empty chairs in a conference room. Not well made but cute.
