Puretext

Have you ever copied some text from a web page or a document and then wanted to paste it as simple text into another application without getting all the formatting from the original source? PureText makes this simple by adding a new Windows hot-key (default is WINDOWS+V) that allows you to paste text to any application without formatting.

Paper Changer

Paper Changer is a small application for changing the background wallpaper on the windows desktop from a random selection of JPEG images within a specified folder. Paper Changer can be set to change the wallpaper every time that you start Windows (without remaining loaded) or just used to change the wallpaper whenever you get bored of the current picture. Paper Changer stretches the image to fit as much of the desktop as possible without distorting it.
