This is a really cool idea. You can create your own quick picture of Albert Einstein teaching a class and writing something with chalk on a blackboard. You just type in your text, and pronto, the picture gets created, and it does look quite authentic–although not authentic enough to stand witness but good enough to bring a few laughs!
To get your own Einstein picture, go to Hetemeel.com. They have several other image generators including one of George Bush and also Microsoft Clippy!
You can probably use these pictures in your next PowerPoint presentation?
