This project for my metal working class, as the title implies, was to build some kind of wall out of metal.  I took a somewhat less literal approach.  I welded pieces of metal together to build a large metal frame to hold a green screen.  I also used metal wire to tie the green cloth to the frame.  For the critique, I aimed my camera (which was hooked up to my computer) at the green screen and projected different walls on the… well on the room’s wall.  As students stood in front of the green screen “wall,” they would find themselves standing in front of famous walls such as the Great Wall of China, the Berlin Wall, and the Vietnam Memorial.    I had created a physical wall that virtually transported those in front of it to other physical walls around the world!  This, of course, is done nearly everyday on the news and such, but it’s still a pretty neat concept to think about 😛
