When I think about randomness and computation, the first thing that comes into my mind is random number/word generator. While it is a very simple program, I think it inspires people to utilize that randomness to create something. For example, there is a singer who uses random word generator and uses 3-5 random words to start creating an entire song at the spot, and although this is not directly related computational projects, I think this interaction between humans and computers to create art is truly fascinating!
