Overhead Projector with LCD

What's the difference between an overhead projector and an LCD projector?

Overhead projectors refer to an old way of throwing an image onto a screen. It's the thing where you put a transparency on a piece of glass with a light under it. The image shoots straight up into an arm unit that bounces the image off a mirror and puts it on a wall or screen. In high school that's what all my teachers used.

When I was in college they used lcd projectors and a computer. These hook up to computers and project whatever the screen is. In my case, that was powerpoint presentations.

Hope this helps. Here's wiki's if you want more.
