It is relatively rare, but software itself (not just the resulting program, such as "a game") can be art. Most examples of this focus on using code to communicate something humorous about the culture surrounding software. I cite FizzBuzz Enterprise Edition [0] as a notable example. There's also code poetry, which encompasses quite a bit more than just humor.
