Reflections: Executable or Text Version
Using just the reflections routine from the foregoing Fractal Landscape program, you can take any .jpg file listed in your standard C:/Documents and Settings/Owner/My Documents/My Pictures/ file on your PC, and make a reflection of it.

Fisheye: Executable or Text Version
Take any of your .jpg or .bmp photos and view them as though taken with a fisheye lens.

For the Text version, you'll need to choose your own background pic, or disable the feature.
Hue Changer: Executable or Text Version

This works very effectively even for example with a car-body with many reflections and shadows (see below).
