In Lovecraft's short story "The Call of Cthulhu," a group of sailors find themselves stranded on the ancient city of R'lyeh - the home of Cthulhu. R'lyeh is described in the story as Non-Euclidean; Lovecraft seems to imply that it is indescribable.
What if, with technology, you could explore that world. Bring to life a world that defies standard connotations of space. That is the premise that drove the creation of this raytracer.
Right now, it is in a very early stage, but I hope to turn it into a fully-fledged puzzle game one day.
