#procjam is a jam about making generative software - computer programs that make things when you run them, like art, music, games, stories, wallpapers, recipes, poetry or anything else you can think of. It's an exciting, different way to be creative, and PROCJAM is here to help you get started, find friends, and have fun with it!

Find tutorials, art packs, expert talks, zines and more on our site:

#procjam just has one rule: Make Something That Makes Something. You can enter a Twitterbot, a videogame, a dice table, an artwork, anything you can think of. Whatever you make, let us know what you're up to! Tweet with the hashtag #procjam and don't forget to submit your work to the jam using this page when you're done.

PROCJAM is for everyone. Here are some things you need to know:

  • You can start early, or finish late. Our jam dates are really just there to let you know when other people will be jamming, so you can make friends and see cool work. Some people can only work on weekends, some people can only take an evening here or there. Some people submit six weeks late, or ten days early. PROCJAM is here for you throughout the year - just tweet at us if you need a late submission code.
  • Your work belongs here. Don't worry if it's a game, or if it's "really art", or if it's "proper" procedural generation (that doesn't exist). We want to see what you've made, because it's inspiring, entertaining and motivating to see what people are doing!
  • Make something physical. We've had paper-and-pen entries before, so don't feel left out if you have a non-digital idea! will still accept the submission too - send us photographs or printouts!
  • Every entry has a place. Some people submit complex works of art that they needed decades of experience to create. Other people submit their very first procedural project here. Our community is friendly and welcoming, and we're excited to see everything that you make!

Earlier this year we asked people what they wanted from PROCJAM, and the number one answer was: more PROCJAM! So this year we're experimenting with a bonus Summer Jam. It's the same PROCJAM you know and love, but without all the extra bits like talks and videos (they'll be returning in November for our main event!)

We have amazing resources you can use that we've built up over the last four years, including:

Free art packs

Tutorials in English and Spanish

Our free zine, Seeds

Hours of free talks by experts

Our summer jam has some optional summer themes! If you want to get a theme, pick your favourite from the list above, or roll a dice to pick one randomly! You can also use this tool from

We also have a special optional challenge for people this year! It's perfect for people who are looking to do something a little more relaxed but still take part in PROCJAM. Sometimes jams can feel like they're all about working too hard and burning out. For this challenge, we're asking you to spend no more than one hour a day on your PROCJAM entry. A perfect way to do this is to make a Twitterbot with Cheap Bots Done Quick. You can get your bot up and running very quickly, and then gently add text to it throughout the week.

Whatever you make, however you make it, and whenever you finish it - please, please let us know and keep in touch. You can find our Discord details on our website, or post on Twitter with the #procjam hashtag! Happy generating!
