Formulas Rendering Plug-In for the Gimp 2
The Formulas Rendering Plug-In for the Gimp 2 is a simple plugin that allows you to change the values of each color channel of each pixel of a layer by using mathematical expressions. It is able to handle RGB* and Gray* images. Available operators are: +, -, *, /, ^, and %. There are many functions available, such as sin, cos, sqrt, abs, min, max. A few constants are provided (pi, e, j), and a lot of pre-defined variables are usable (w for image's width, h for image's height, x and y for cartesian coordinates in the image, etc.).

I think this plugin is neat because it updates the preview in real time as you are typing the formulas in. It's nice just to see what happens. Very cool.
