A fisheye lens for ten bucks - made from a door peep hole you can pick up at Lowe's. I remember seeing a story like this years ago in Popular Photography Magazine years ago. I used a "screw on" lens cap when I made my first fisheye lens - but, of course, that was the pro version. Here is an even cheaper way to do it, and it will work with your point and shoot camera. How do you do it - here is the link. Check out the images right here. Just all in good fun.
