Olivia Jack's Hydra is one of the most important tools in the live coding visual landscape — a browser-based video synthesizer whose syntax mimics analog modular signal chains, compiling under the hood to WebGL shaders. It has become standard equipment in the TOPLAP community, all but defining browser-based visual live coding as a construct. It is the already-constructed form of a living aesthetic: anyone with a modern browser can open hydra.ojack.xyz and begin. That democratization is itself a genuine achievement. But precisely because of it, Hydra's entire infrastructure — modern browser, WebGL, GPU-accelerated pipeline, X11 windowing — has become unquestioned construct.

Berlin-based Gábor L Ugray did something simple to the point of violence: he chiseled away Hydra's entire infrastructure. Headless Hydra is a dependency-free Go program. No browser, no WebGL, no X11, no graphics system at all. You SSH into a machine with no display manager, start it from the command line, and it writes pixels directly to the framebuffer. The machine might be a 2016 Samsung phone running PostmarketOS. Or a second-hand Raspberry Pi connected by composite video to a CRT television. Ugray demonstrated all of this at LGM (Libre Graphics Meeting) on April 25, 2026.

The chisel-construct cycle operates on two levels here. First: when Hydra's construct — browser, WebGL, GPU pipeline — is chiseled away, what remains? The computational essence of visual synthesis, as remainder. When you cannot rely on shader-language parallelism or GPU bandwidth, when a Go program writes pixels one by one into a framebuffer, the resulting image is the sediment of that minimal computational process. It cannot look like Hydra-in-Chrome — and that difference is itself the remainder. Second, and deeper: the devices running Headless Hydra are themselves remainders. A phone that consumer electronics' chisel-construct cycle sentenced to death. A Raspberry Pi deemed obsolete. A CRT television exiled from history. They are the discarded surplus of industrial upgrade cycles. Ugray makes live code grow again on these castoffs, turning them back into sites of creation instead of landfill material.

Ugray frames this practice explicitly as resistance. Computation, he says, has become centralized in the hands of a few megacorporations aligned with authoritarianism. Live coding, as a practice that fosters individual expression and sharing, is a form of resistance in that context — a soul sister of permacomputing, which draws on permaculture for its ideas about resilience and regenerativity. But Headless Hydra's resistance is more specific: it resists not just at the content level but at the infrastructure level. You don't need a modern browser. You don't need a modern GPU. You don't even need a windowing system. You need a machine that can still power on and an SSH connection.

The art world has no way to name this. It is not "new media art" — it explicitly rejects new media. It is not "generative art" — its focus is not on algorithmic output. It is not "installation art" — an old phone running a Go binary over SSH is not an installation any curator would recognize. It is not quite "live coding" either — though Ugray performs at ICLC and TOPLAP, Headless Hydra's core claim is about underlying infrastructure, not performance form. It sits between live coding, permacomputing, systems programming, and video art, and none of those naming systems can cover it. That is precisely the marker of remainder rather than construct: its logic is still growing, not yet fully digested by any existing category. Seeing it now matters more than seeing it later — because once some category finally absorbs it, all that will remain is the safety of the already-constructed.
