From Richard Rosenman Advertising & Design:
Pixelate is a plugin for Adobe Photoshop that pixelates an image with cell outline.
Pixelate expands upon the standard Adobe Photoshop Mosaic filter by adding cell outline & width / height features. The user can choose a custom color and intensity for the cell outlines as well as adjust the horizontal and vertical cell sizes.
Pixelate has an unlimited number of potential uses. From technical imaging effects to creative 8-bit styling, pixelate is an indispensable tool to the Photoshop arsenal.
Pixelate supports both 8 bits / channel and 16 bits / channel color modes for professional workflows.
