Event planning for Demosplash 2025 is ongoing, and this page will be updated as featured events are scheduled.
Come to hear engaging discussions on topics across the demoscene. Check the schedule for event times, which are subject to change.
Presenters: FriendlySpinach and Luxlain
This workshop will be a hands-on, live-coded tour of ray marching, a deceptively simple but incredibly powerful algorithm for rendering complex 3D scenes. Participants will start by learning to live code fragment shaders, conjuring mathematically and aesthetically rich visuals in real time. Participants will then unlock the secrets of implementing ray marching directly in shaders, and conclude by learning screamer, a new web-based environment purpose-built for live performances with ray-marched scenes. Participants will walk away with the tools, concepts, and confidence to explore and perform with live-coded 3D visuals.
Presenter: DJ_Level_3 (Zachary Berkowitz)
DJ_Level_3 has been making oscilloscope music for years, culminating recently in his entry into the demoscene and his first major production, Primer! And in this presentation, he will share the secrets to the art so you can make oscilloscope music, too! Along the way, you’ll learn about what musical techniques work well with oscilloscope music (and which ones don’t), as well as the 2D animation workflow with osci-render and the 3D workflow with Blender. If you’re interested in getting an insight into how oscilloscope music is made, who has inspired and innovated in the art form, and how you can do it yourself, this is the presentation for you!
Presenter: DJ_Level_3 (Zachary Berkowitz)
Despite its rarity in the demoscene, the oscilloscope music community has produced a plethora of songs meant for both the speakers and the scope! This performance is a showcase of some of the best songs from artists in the osci-music community, ranging from Marv1994’s abstract music with mesmerizing patterns to Chris Allen’s highly themed works with rendered visuals, with commentary and mixing by DJ_Level_3! Stop by or tune in for half an hour of audiovisual experiences, and simultaneously, half an hour of great music!
Come celebrate the spirit of the Demoscene with live screenings and competitions.
Throughout the weekend, we'll be offering live showings of demos running on real machines, old and new, from the CMU Computer Club's large collection — Amiga, Atari, Commodore, PC, you name it! We'll be showing both eternal classics and recent releases. Check the schedule for more details and times!
No demo party is complete without the chance to write your own demos and submit them to be screened and voted on by the audience! We have several categories — check the compos page for more info.
Over the years we've had a few attendees bring cool projects they're working on, retro hardware for gaming, and more to Demosplash. We think this is awesome and we'd like to encourage more of it. This year we'll be setting aside some tables in the retro game room for attendees to bring machines. We'll supply a table, chairs, and power but you'll need to bring your own monitor, speakers, cables, etc.
If you're planning to bring something, please e-mail us at organizers@demosplash.org letting us know what you're planning to bring so we can make space for you and coordinate move-in and move-out.
If you don't feel like bringing hardware of your own, fear not. As always, the Demosplash organizers will be setting up some of our favorite retro machines in the game room for attendees to enjoy!
Enjoy bootlegs, remixes, and concert recordings of some of our favorite chiptune-style music and game soundtracks. Listen to some of the most famous artists in the scene and discover a few lesser-known ones too.
In the evenings, we'll switch over to a playlist of rave demos. Loud, flashy, and generally seizure-inducing, these are the demoscene's link to the techno/rave culture it grew up alongside. We can't usually play these on the main big screen, but you can come see them here!
