Work you can press play on.

Original pieces and concept projects from both doors. Concept projects use fictional brands and synthetic data, and say so.

Door 01

Deinorus Studio 3D, motion and real-time

What Studio builds
Wickwren, a stylized hooded character holding a glowing lantern at night, rendered in Unreal Engine 5

3D character / Unreal Engine 5, path traced

Wickwren

A hooded lantern-keeper built from scratch: model, 33-bone rig and six animation clips, delivered as a game-ready FBX pack. Key poses plus procedural animation, no mocap and no generative AI. The video is rendered in Unreal Engine 5 with path tracing.

  • Unreal Engine 5
  • Blender
  • Rigged + 6 clips
  • FBX pack

Toaster Showdown: a grumpy grandpa stares down a cartoon toaster in a pink 2000s-style kitchen

2D animation / short

Toaster Showdown

A 35-second cartoon short in bold 2000s TV style: original character, real walk cycles, comic timing and a synced score. Animated entirely in code, with no AI image or video generation.

  • Cairo
  • Sound design in code

Phoenix A black hole: a luminous accretion disk bent by gravity around a dark shadow

Scientific visualization / WebGL

Phoenix A, physics-true black hole

How a spinning black hole of about 100 billion suns (estimated) would really look. Every pixel follows a light ray through Kerr spacetime, in a ray tracer coded from scratch in WebGL. No AI.

  • WebGL
  • GLSL
  • Ray tracing

Door 02

Deinorus Lab AI and machine learning

What Lab builds
Title card of the Deinorus Fall Detector demo video

Own product / computer vision

Deinorus Fall Detector

Watches a care-home room through an ordinary camera and alerts staff when it detects a fall, even if the person gets back up. If they stay down, the alert escalates, and only a staff member can close it. A pose model turns each frame into a skeleton, so the alert engine and the staff panel only receive skeletons, zones and events.

  • Pose estimation
  • Temporal model
  • Alert engine
  • Staff dashboard

Input footage is AI-generated; the detection is real.

RAG over PDFs: a trace view with version filter, hybrid search and reranking

Concept project / LLM + retrieval

RAG over PDFs with evals

Answers with the page it used, refuses when the answer is not in the documents and ignores instructions planted in them, with a regression gate on top. Fictional company, synthetic documents.

Held-out test set: 0 of 7 planted injections obeyed, 10 of 10 unanswerable questions refused.

  • Hybrid search
  • Reranking
  • Eval harness

AI agent evals: scenario results and a regression gate turning red

Concept project / AI agents

AI agent with tools and evals

A customer-support agent with 7 tools, human approval above a limit and guards for tool failures. Evals judge the backend's final state against a hidden answer key, not with an LLM. Fictional store, synthetic data.

Held-out scenarios: 99.4% solved, 0 critical violations.

  • 7 tools
  • Guards
  • Regression gate

n8n intake workflow: 200 synthetic requests scored against an answer key

Concept project / automation

n8n intake workflow

Maintenance requests are validated, deduplicated and classified by category and urgency with a language model, then answered and announced with retries and alerts. Fictional company.

Tested on 200 synthetic requests against a hidden answer key.

  • n8n
  • LLM classification

Door 01 / Deinorus Studio

Characters that move, ready for your engine.

3D production for games, apps and the web. Stylized and fantasy work is the sweet spot: creatures, heroes and cartoon characters, not photoreal humans.

  • 01

    Stylized 3D characters

    Modeling and rigging for fantasy characters and creatures, delivered ready for Unity, Unreal or Roblox.

  • 02

    Motion capture

    In-house Rokoko Smartsuit Pro and Smartgloves: full body and finger capture, so hands act too.

  • 03

    Animation

    Cycles and custom performances for your characters, game-ready or for video.

  • 04

    Video and motion graphics

    Product videos, explainers and animated pieces built around your 3D and your brand.

  • 05

    3D for the web

    Interactive 3D in the browser with Three.js and WebGL, light enough to run on a phone.

  • 06

    Mocap animation packs

    Coming soon to Fab and Unity Asset Store.

    Coming soon

Door 02 / Deinorus Lab

Machine learning, built around your data.

Applied AI and research. Models and agents with a defined job, not a demo that falls apart on real inputs.

  • 01

    Custom models

    Machine learning models trained for your data and your task.

  • 02

    LLM fine-tuning

    Adapt a language model to your domain, your format and your tone.

  • 03

    Agents and automation

    AI agents that take over repetitive work with tools, memory and clear limits.

  • 04

    Computer vision

    Pose-based detection from video. A human-pose fall detector is a finished in-house project.

  • 05

    Research: Deinorus Attention

    Subquadratic attention that retrofits existing LLMs without retraining them. Work in progress.
