Image Disturb is an original java graphic application. It let you apply effects to 24-bit images. The effects are geometric, convolution, and color transformations. The color transformation is the more interesting feature, it let you to apply a transformation globally, or locally by recursion, and can also be limited to geometric zone (the zone and the effect can be moduled with mathematic function, e.g gauss, square, ..). Drawing functions are available, too. It lets you paint with pencil, part of image or color effect.
