Mattias Kramm shakes up Revision 2025 with a signal swap that’s as clever as it is chaotic.
Most demos stick to the script. This one plugs in backward—and makes it work.
At Revision 2025, Mattias Kramm unveiled Signal Carnival, a demo that crosses the audio and video cables from the Commodore 64. Yep, on purpose. And this isn’t just retro hardware abuse for shock value—it’s an actual working demo that turns signal confusion into synchronized creativity.
Now, this kind of cable mischief has roots in the ‘90s. Back then, tinkerers would sometimes hook up audio to video inputs and vice versa, just to watch the screen pulse along with the beat. It was a quirky party trick, but mostly chaotic and random.
Kramm’s take is far more ambitious. Signal Carnival not only flips the cables—it still manages to deliver recognizable sound and visuals. Video runs through the audio line, audio through the video line, and somehow it all still clicks together in a way that’s structured and intentional. It’s a technical stunt, but also a functioning production—and that’s a first.
The result? A Commodore 64 demo that feels like it was pulled straight out of a hardware fever dream—but one with rhythm and purpose. It’s part experiment, part spectacle, and all clever.
