I will be teaching only one lecture on basic Prolog to students with little to no experience in programming. I'd like them to see that programming and Prolog can be used in the real world, perhaps even to do cool things.
I have looked at this and this threads, but I cannot find anything that is visually appealing that I can show them when we wrap up the lecture.
Do you have any suggestions for cool applications that use Prolog? I'm especially looking for something that can be shown as a video or slideshow.
