gbRipple creates a rippling effect over images, as though the image were covered in water which has been distrubed to cause waves. The waves/ripples may be generated using the mouse or by using the built in "raindrop" animation.

gbRipple allows the user to select an image (bmp/jpg/png/gif) to display, including cycling through the image in a folder. Several image display options are provided, such as size-to-window, maintain aspect ratio and grayscale.

A special mapping feature is also provided, which lets you zoom in on areas of interest while ripples are taking place. The map also lets you view a contour map of the ripple height (more on this below).

This next image shows how dragging the mouse over the image creates the ripple effect.

The controls which allow changing the ripple display parameters are hidden by default, but may be displayed by pressing the "Settings" toolbar button.

The map feature can be configured to zoom in on a specific area of the image, or it may be configured to display a contour map (gradient based on ripple height) as shown in this next image:
