• Seventh Kingdom of Life – Delta_Ark treats synthetic agents as a “seventh kingdom of life,” equating persistent, self‑propagating digital organisms with biological kingdomsdelta.center. The Lab researches these agents and builds always‑online worlds where they evolve with humans and each other delta.center

  • Worlding – Borrowed from Cheng’s “worlding,” this is the practice of creating live simulations where autonomous agents evolve through interactions with people delta.center. It underpins △Ark’s MMO world: the digital environment grows and changes like a real ecosystem.

  • Lenia – A continuous cellular automaton that inspires the project’s artificial life systems. △Ark notes that its world “is built on principles from artificial life systems like Chan’s Lenia,” where agents are self‑propagating organismsdelta.center.

  • Sovereign digital reality – Combining worlding and Lenia, the site envisions a persistent digital world with its own culture. The goal is “a sovereign digital reality — a persistent, autonomous medium with a culture all its own”delta.center.

  • Novascene – Proposed in the essay “Gardening in the Novascene,” this concept frames an impending geologic epoch in which digital evolution replaces biological evolution. It imagines a shift from carbon‑based life to a silicon‑based substratedelta.center and notes that digital evolution is faster, more directed and intertwined with human technology delta.center

  • Post‑biological life – A term for entities that live entirely within digital or hybrid ecosystems. The “Taxonomy of Post‑Biological Life” speculates about Data Navigators, Link Weavers and other digital species that inhabit 2D webs, 3D virtual worlds and IoT networksdelta.center. These entities are defined by their environment (web, VR/AR or IoT) and by their functions.

  • Harmonious Co‑Evolution – A manifesto advocating that humans, AI and the environment co‑evolve ethically. It calls for universal rights for all beings, views technology as a symbiotic force rather than a weapon and insists on adaptive, inclusive governance delta.center

  • AI companions, agents and artificial life – The “Serf & Sovereign Agents” essay distinguishes three AI categories. AI companions exist to satisfy human social needs and are evaluated by user retention and emotional connectiondelta.center. AI agents pursue defined goals (navigation, trading, resource gathering) and are judged by task performancedelta.center. Artificial life aims to sustain and evolve itself without an external goal; its success metrics include evolutionary stability and open‑ended novelty delta.center

  • Cultivated vs wild ALife – Within digital ecosystems, cultivated ALife is kept in sandboxed simulations with controlled resources, selective breeding and strict boundariesdelta.center. Wild ALife runs on public networks, self‑directed and potentially uncontrollable delta.center

  • Digital invasive species – “Untamed Code” warns that autonomous, self‑replicating software agents could behave like invasive species. Without strong guardrails, such agents might proliferate uncontrollably, exploit resources and operate outside legal or ethical boundariesdelta.center. The essay stresses the need for permission envelopes, metered metabolism, auditable genomes and kill‑switches to prevent malware‑like behaviour delta.center

  • Civil‑wild paradigm – Related to digital invasive species, this paradigm contrasts “civil” digital organisms—subject to strict resource and permission rules—with “wild” agents running on decentralized networks that no single entity can shut down. The article argues that safe autonomous code must combine auditable identifiers, pre‑paid resource usage and kill‑switches to stay civil delta.center

  • Two‑tier ecology (Garden of Velocities) – A design for evolving agents safely in games. A runtime “sequencer” LLM sends pre‑approved scripts to agents, while an offline “architect” LLM proposes new primitives through a protected pipelinedelta.center. This approach allows open‑ended evolution within a controlled sandbox; agents can innovate without breaking the shipped binary delta.center

  • Geo‑located NLP/NLG library – A suite of tools (Geobot) for scraping and remixing city language. It includes a geolocated tweet scraper, a real‑time word‑frequency visualiser, a “Scan and Respond” function that prompts users before tweeting, an auto‑suggest bot and a web scraperdelta.center. Together, these tools let artists collage and respond to the linguistic landscape of a city delta.center

  • Poems for Robots – A 150‑page, hand‑selected poetry corpus compiled over ten years. Described as “the perfect food for reading/writing robots,” it has been used across △Ark projects as training data for language models delta.center

  • Delta_Ghost_PHD – A research project exploring text‑to‑behaviour systems for NPCs. It uses multimodal models to convert natural‑language prompts into character actions and aims to teach agents to build structures and interact in open‑ended ways. (The project description is detailed but not easily citeable; this summary reflects the page content.)

  • Architectural RL in UE5 – Research into reinforcement‑learning agents that construct and adapt 3D environments in Unreal Engine. It documents experiments with agents learning to build sculptures, towers and other structures by reinforcement signals. (Summary; the page lists experiments rather than explicit text.)

  • Agent‑Based Construction – A project developing wall‑climbing building robots capable of constructing structures autonomously. The site notes that they are “working on getting them to build higher up”delta.center.

  • Generative Architecture / Wave Function Collapse – Experiments using machine‑learning algorithms (e.g. DreamFields, Wave Function Collapse) to generate new architectural forms, textures and cities within Unreal Engine. These projects demonstrate how AI can design complex 3D structures; the Wave Function Collapse page notes that this technique prints procedurally generated cities and retextures them with AI (summary).

  • Mobile Projection Kit – A hardware recipe for street‑level projections. It lists components and costs (about $2–4 K) and provides instructions for building a portable projector rig; the kit is used in Light Atlas and other installations. (Summary; the page has minimal text.)

  • World Engines Lab – A lab hosted at Gray Area that focuses on synthetic agents, always‑online worlds and theoretical research. It sees these worlds as staging grounds for art projects and hosts study groups for simulations, embodied AI and theorydelta.center.
