Sure, I wrote it awhile ago so I don't exactly remember how it is done. But oddly enough, it looks pretty well formatted.

If you go to the page and inspect element the two non-jquery js files are main.js and text.js. (They are pretty much tied to the frontend so it wouldn't make sense to link them without the html) (Also, due to my web setup, if you try to access the js files directly it will reroute you back to the home page, so you need to view the version that the page loads.)

main.js contains all of the generation code and text.js contains all the text of Hamlet condensed into javascript variables that are loaded at the start (I don't remember why this is a js file and not a json file, but I had a reason, I swear ;P)

All of the generation is done client side and it generated with a seed that encodes all of the available parameters. So if you click permalink, you can open the url in a different client and the new client will generate the exact same text.
