Till Nowak’s Salad is a digital rendition of Alien made out of vegetables. (currently Till’s site won’t load…)
It was shown at the Emerging Technologies of Siggraph 2007.
From Laughing Squid:
Till Nowak modeled twelve digital vegetables in 3ds Max using classical polygon modeling techniques. Photographs of fresh vegetables were used for the texturing process. Most of the vegetables started with a cylinder primitive and needed around 30 minutes of work. The modeling was easy – it was much more difficult to find the right places and orientations to build a monster with it.
