I found a nice piece of work which use this technique to produce a master piece.
example:
In computer graphics, pixelation (or pixellation in UK English) is an effect caused by displaying a bitmap or a section of a bitmap at such a large size that individual pixels, small single-colored square display elements that comprise the bitmap, are visible to the eye.
In the real-time of 3D computer graphics, pixelation can be a problem. Here, bitmaps are applied to polygons as textures. As a camera approaches a textured polygon, simplisticnearest neighbor texture filtering would simply zoom in on the bitmap, creating drastic pixelation. The most common solution is a technique called pixel interpolation that smoothly blends or interpolates the color of one pixel into the color of the next adjacent pixel at high levels of zoom. This creates a more organic, but also much blurrier image. There are a number of ways of doing this; see texture filtering for details.Early graphical applications such as video games ran at very lowresolutions with a small number of colors, and so had easily visible pixels. The resulting sharp edges gave curved objects and diagonal lines an unnatural appearance. However, when the number of available colors increased to 256, it was possible to gainfully employ antialiasing to smooth the appearance of low-resolution objects, not eliminating pixelation but making it less jarring to the eye. Higher resolutions would soon make this type of pixelation all but invisible on the screen, but pixelation is still visible if a low-resolution image is printed on paper.
Pixelation is a problem unique to bitmaps. Alternatives such as vector graphics or purely geometric polygon models can scale to any level of detail. This is one reason vector graphics are popular for printing — most modern computer monitors have a resolution of about 100 dots per inch, and at 300 dots per inch printed documents have about 9 times as many pixels per unit of area as a screen. Another solution sometimes used is algorithmic textures, textures such as fractals that can be generated on-the-fly at arbitrary levels of detail.
