Game jams have already begun encouraging creative, improvisatory game jam, by gathering designers and artists together and motivating them with tight deadlines. But here’s a new concept: what if all the games could talk to one another? What if they could all respond to the same basic game inputs, but with differing results?

Using the network protocol OpenSoundControl (OSC), a game jam this week tests what would happen. Each game is both transmitter and receiver, dealing with the position and color of a player (in two-dimensional space), and position and color of an “entity” (be that an alien, a hamburger, or whatever you’ve added to your game).

Beyond that, everything is open to you, the designer(s) – meaning this could cover quite a lot of ground.

OSC’s name is misleading in that it never necessarily had to do with sound; it’s really just a way to standardize real-time communication over a network. As the organizer puts it, “a shared network protocol means that all the games made for the jam can be hooked up to each other, with chaotic, unpredictable, and exciting! results.” But to aid those less familiar with the protocol, there’s even a free download in Lua that does the work of implementing the protocol for you.

For a further explanation, rules, links to helpful OSC libraries for game engines like Unity, and more, see the thread on an indie game forum:

EXCOSC game jam Aug 17th-24th

There’s apparently some flexibility with the dates, as well, if that makes a difference.

We hope some CDMers get involved – let us know if you do, and we’ll feature your work! (Take screencasts, etc.!)


  • Hey all – this is REALLY exciting to see!!

    You might scope illucia.com (forgive, it is almost-launched, messy/beta at this moment) You’ll find:

    a suite of free OSC games with source code, and Max utilities
    Open Source Hardware patchbay controllers
    Hermes, a game library for Processing that supports OSC

    Feel free to reach out via @paperkettle:disqus (or illucia.com/contact/) if you need any help!!

    Hi! I’m organising the event – it’s great to see it pop up here 🙂

    I’ve tried to make it as easy as possible for people to take part – as well as the skeleton lua project, I’ve just uploaded a combined game launcher/patcher which will make it easier to connect up the games. If there’s anything more I can do, please let me know.

    Also, Chris definitely deserves a shout out, as it was his War Machine game that inspired this jam in the first place 🙂
