I happen to be a big fan of antiquated things.  I like looking at things that used to be the latest and greatest, but are now basically reduced to objects, no longer serving their original function.  Case in point, the overhead projector, which has since been replaced by sleeker, smaller, ceiling-mounted projectors that connect to computers.  When I was a kid, I was fascinated how you could photocopy onto a clear piece of paper and enlarge that image so that the whole classroom could see it all at once.   The light bulb was so strong that it would illuminate every spec of dust that blew by, which was both cool and gross at the same time.   So here’s to you, Overhead projector, forever honored in this piece.
