Piet

Hello World in Piet with the matching pixel art by Kelly Boothby.

Another great work of art is Matthias Ernst piet programm which inteprets brainfuck.

There are also attempts to write a piet program and a piet like art work.

One last great example for a piet program which I like a lot is by Richard Mitton. This program calculates an approximation of pi by dividing a circular area by the radius twice. A more accurate value can be obtained by using a bigger program and therewith circle :)

AllRGB

The objective of allRGB is simple: To create images with one pixel for every RGB color (16,777,216); not one color missing, and not one color twice.

This picture from yashe includes it's own code.
