I have been delving into Interactive Fiction lately, becoming more consumed by both reading (watching, playing) branching fiction stories (Choose Your Own Adventure, or CYOA) and the like. Zork is probably the first digital instance of branching fiction. There is an annual competition of IF stories (record 72 submissions) you can try out if you like.
I also read a lot of science fiction, the latest being D.O.D.O. by Neal Stephenson (my favorite author) and Nicole Galland, collaborator with Neal and 4 others on The Mongoliad Trilogy (another kind of interactiveness). D.O.D.O. is a story about magic, and its recursive recovery and application in modern times through time travel. A very complicated treatment of time travel, with varios threads of the story intertwining like the infinite branches in the universe.
I teach a course that uses Twine for students to create their own interactive fiction. I find it the easiest of the different story engines (word processors for branching fiction) out there.
So when I saw this video, it made me happy to see a physicist treat the plots of time travel movies in such a logical way. This is important to both Interactive Fiction (IF) and storytelling.
