I remember I just through this together really quickly. It comes from a bunch of experiments I ran before where I used the status line to communicate with javascript to do whatever I wanted. It has the advantage of not needing a server like Vorple does, and has the disadvantage of making it harder to set the status line for normal usage. It also runs off of standard Quixe, so it’s hard to make it do anything besides ‘quixe in one jframe with other stuff around it’.
The reason I personally didn’t do anything more with it is because I’m not very interested in graphical games, but I did use the same trick to add location music and colors to Absence of Law.
In the end, I think Worldsmith ended up using a similar trick. Have you tried that game? It has complete multimedia integration (with videos and more) and is a huge parser game. It has a sort of civilization/world-building minigame but once you get past that it also has an enormous 10+hour parser storyline.
