Leander Herzog: runtime

virtual.hek.ch

30.01. – 30.03.2026

For sixty days, Herzog takes over the HEK (House of Electronic Arts) homepage where it becomes a site of continuous algorithmic execution. One work exhibited each day, fullscreen, running in realtime, which is to say perpetually generating itself. There is never a static frame to capture, no single moment that recurs. The browser window is not a viewport onto documentation but the work's actual substrate: HTML, CSS, JavaScript, SVG rendered live on any screen that encounters it. This is a daily takeover of a museum's online space, the institutional website transformed into digital exhibition surface. Open hek.ch and encounter the work before anything else, at full scale, without mediation, in its fully digitally native form.

Leander Herzog has selected sixty works spanning a decade of practice, from 2015 to 2025. What distinguishes this presentation is its refusal of the archive as static repository. These sixty works exist across digital platforms and blockchains. The distributed nature of onchain practice typically fragments viewing into platform-specific encounters. Runtime proposes consolidation: all of it, accessible in sequence, executable in the browser, without navigation between arbitrary ecosystems.

Herzog's approach to computation has always resisted spectacle. There is no apparatus beyond the browser, no blockchain mechanic foregrounded as conceptual alibi. The constraint is deliberate: complex results from simple rules, the brutalist position Herzog has maintained throughout his practice. Code operates as medium in the same sense that oil or marble might, with specific material properties, resistances, affordances. These works respond to viewport dimensions, readjusting composition when the display window changes. They respond to temporal conditions, shifting with diurnal cycles or evolving over days, they exist as systems rather than files, each execution a singular instantiation of underlying logic.

Each work carries provenance inscribed on its respective chain. The selection is populated by familiar collector addresses, 0xfff, Andreas Gysin, Kim Asendorf, Kevin Abosch, HEK, ZKM, LeRandom, Snowfro, Marius Watz, Celadoor, alongside anonymous wallets. This is not incidental. The network of collectors maps a decade of relationships within generative art: early supporters, collaborators, peers whose practices intersect with Herzog's. Ownership here functions less as possession than as participation in a sustained conversation and an emerging movement.

The selection of works shown is not chronological but relational, tracing how ideas migrate between bodies of work, how formal challenges resurface and resolve across years of iteration and refinement. Agglo as individual generative outputs leading to synchronised Agglo on a skyscraper in the UK; 1000 True Fans anticipates participatory Infinite Garden in New York; the DOM trilogy, a collaboration with Milian Mori that was conceived as commission for HEK Basel, shares material sensibility with Heatsink; Downloads establishes the conditions for smart-contract-based Abo; Microwave was the study and Fract its conclusion. Watched in sequenced survey, what emerges is not a retrospective but a map of recursive investigation. Some works demanded inclusion by virtue of their position in the practice: Time (2018) could not be absent; Shipping marked Herzog's first interactive mint; Returns, his first longform series. Others appear because of formal resonances that reveal themselves only in proximity, like the trajectory from Berg through Fitness to Igel.

  • Leander Herzog] (b. 1984) artist based in Switzerland, creating images with code since 2006. His practice explores the tension between algorithmic simplicity and emergent complexity. Works have been acquired by ZKM Karlsruhe, HEK Basel, and Francisco Carolinum Linz.
  • HEK (House of Electronic Arts Basel) is dedicated to digital culture and new art forms at the interface of art and media technology.

FAQ

What is this?

Web-based generative art: Small programs creating moving images in the browser. Made with code, optimized for online distribution. It's built from web standards: HTML, CSS and javascript. The visually complex work is made with WebGL and GLSL or SVG. Each work is a website, augmented by a smart-contract on a blockchain. Networked objects with credible durability and no external depencies.

What is "realtime"?

The work executes itself, in response to your presence. Instead of a static object, it's a dynamic process, unfolding over time. The code is loaded from a website or blockchain, but the art happens on your computer. This environment is also know as a "runtime".

What does the code look like?

Shipping, Agglo, Deathstar, DOM1

What blockchain is the work on?

The works in this selection are on Eth, Tezos, Base, Shape and Solana. Early works are stored on decentralized storage (IPFS). All the recent works are "onchain": Both ownership and the work itself are stored permanently on the blockchain.

Where can I find more?

On the artists website, platforms like Raster, Objkt or X and Instagram. All works in the selection have a link to their token with detailed information and context.
