I found a random art generator online called random-art.org. When one types in a name, the generator will give you a randomly-drawn image. This program is written by Andrej Bauer, who completed his degree at CMU and is currently teaching at a university in Slovenia. This random art generator is coded using a pseudo-random number generator, which determines the color of each pixel. Because it is based on a pseudo-random number generator, one will always get the same image if he or she types in the same word.
On the website, the creator notes that the program is primarily written in OCaml, but has java script embedded on the web version, and may download a python version if desired.
I find it very interesting that one can use computer to code random images and entertain people!
