There is a bar I frequent in Johnstown PA, the Pheonix.? In this bar they have two large mirrors that meet in a corner. They come together at 90 degrees.? No matter how I move about my image always appears at the place where the two mirrors meet.? I move left and right and there I am in the middle.? It makes my shoulders look really broad.? Its amazing.? I can't explain it.
Perhaps if I could understant it better I could make a lenz that always concentrates light on the same point independent upon the light source's position. Still amazed.? Drinking does not clear the mystery up.? Frank Z
