Re: Sundial inside a room, but room is inside a canyon!

  I have a question for those on this list with more experience (just about anyone!):   What would happen if a mirror were used not to reflect the sun's image, but as the dial itself?   As a kid, I had a mirror with an engraving of a deer on it in my room.  I used to like to play with a flashlight
