Edison 2023: Under the Sea - the computer arts festival in Stockholm

Welcome to an ambitious computer arts festival and a traditional demoparty in Stockholm!

Edison 2023 is the 13th iteration of a 3 day event with competitions in programming, graphics and music as well as a social gathering out at Eggeby Gård on Järvafältet where you can meet old and new friends.

We have space for 150 participants and multiple grassy fields to set up your tents on if hotels just isn’t your thing.

On Friday we focus on battling live on stage against other participants.

On Saturday there’s all the competitions you either are used to or didn’t know existed. Check out our compo page for more details!

July 7th – 9th
Eggeby Gård, Stockholm, Sweden



We’ve finally opened the party system where you can upload your entries and vote on the competitions.

If you get a ticket please give us at least an hour to manually enable your access key before trying to register in the party system. Or ask us on Discord in the #compo channel if you’re in a hurry.


Edison 2023 - Under the Sea PC invitation by jor-el and Fegolhuzz

Every year there’s a demoparty in Uppsala in Sweden.

Members of Edison crew created a PC demo that invites you to Edison and submitted it to the PC Demo competition at Birdie.

This invitation placed 4th out of 8 entries and is now one of our official invitations.

Credits goes to jor-el for programming and Fegolhuzz for the music and graphics.


You can now order t-shirts, pants, hats and a plethora of other apparel from our official Spreadshirt store with the new Under the Sea logo by Fegolhuzz!


We’ve replaced the Live Music Duel compo with a TIC-80 Live Coding compo a.k.a Byte Battle as made popular by LoveByte.

Participants compete against each other by creating visuals using pure TIC-80 code (Lua) and an FFT function generated by the DJ:s music. Pretty much like a Shader Showdown but much, much more accessible.


Did you know that we’re watching demos and drinking beer in a bar in central Stockholm every month?

Join us at Medeltidskrogen Sjätte Tunnan in Gamla Stan (not E-types place) on Monday April 17th. Future dates will be posted here and on Måndagsklubben.net

The bar has a plethora of beer and meads and we got a room to ourselves that’s open for anyone to join.

Great news everyone! Wiklund will be performing his music live on stage at Edison this year!

Wiklund is a Swedish video game composer who started his musical journey in his bedroom in 2008, but has since peformed his music live over 50 times around the globe.

He started out playing around on his old dusty gameboys and later discovered the possibilities of other consoles when he became part of the demoscene.

Two great influences that shaped Wiklund’s music include 80s synthpop and other demoscene composers.
