The Oilpaint effect that ships with the free Pixel Bender plugin for Photoshop CS5 allows users to transform their photographs into images with the visual appearance of oil paintings. With a few simple sliders, users can adjust the amount of stylization, brush-size, brush-scale and other parameters. Thanks to the GPU support that is part of the Pixel Bender technology, these adjustments happen lightning fast on GPU enabled computers.
