A few months ago, I posted a rough translation of the rules to a collaborative fairy tale storytelling game more than 200 years old. I've now put that onto a Neocities site with many additional translations: a total of 5 variants of the same game re-published many times between 1801 and 1867, several variants of a game the same age that involves role-playing, and several variants of even older poetry and nonsense games related to the Surrealist game "Exquisite Corpse." There are also pages and translations explaining the history of the games' penalty phase, offering advice on running demos of the storytelling game especially using motifs from the earliest "secondary world" fantasy novel, and possible round-robin storytelling from the 1600s-1700s, as well as links to many additional sources for parlor games from 1551 to 1899.
I worked up a rough translation of one of the collaborative story-telling games linked in this post: Pre-Surrealist Games. It's called "The Impromptu Tale," and there's a lot to it that modern tabletop gamers may find familiar.
It's an adding and visualization tool. You can create items that have scores, put them in boxes that add the scores up, and then rearrange and resize them in 2D space. Changes are synced in real-time across browsers, so someone can watch your changes if you're working on a public board. [more inside]
You see an abandoned on the city street. You list it. Anyone can claim it. Basically we've developed an app that whenever you see something like a couch, TV, BBQ, etc. that's been dumped on a street corner, you whip out your iPhone and take a picture of it. The item goes onto a big map, so that anyone can browse and get it for free!
A multi-threaded writing project and collaborative world-building exercise. Stories on main site, world-building and interactive collaborative write-and-share on associated message board. Set in one of those terribly derivative futuristic *punk dystopias. Punkpunk, in this case. Just launched so at the moment the only contributors are myself (I've done all the posts on the blog so far) and a couple of friends (on the forum), but it's open to anyone whose imagination is sparked by it.
