A fake terminal. A coding agent starts building a little Rive scene, and partway through, something else starts typing.

I used both the Rive CLI and GPU Canvas. The agent wrote the scene in RML through the CLI. The terminal renders to an offscreen GPU Canvas and runs through a CRT shader I wrote in WGSL. A state machine and some Luau scripts handle the typing.

The whole thing runs off one data-bound number I called "possession." As it climbs, the text, the cursor, the shader and the preview window all go wrong together.

I did the preview animations by hand in the Rive Editor.

I'd never opened @Rive until a few days ago.

Inspiring creative work.

Halloween Hotel: a crooked Gothic hotel under a giant moon. Click the windows to catch 15 famous monsters mid-routine (Dracula shaving at a mirror with no reflection, the Mummy wrapping himself in toilet paper, the Grim Reaper working the front desk) and find them all before sunrise. Every set of three you finish plays a reward, and finding everyone finally lights up the NO VACANCY sign.

How it was built: I modeled and baked the hotel in Blender, and it runs as real-time 3D (140k triangles) inside Rive's GPU Canvas, with custom WGSL shaders for the sway, the shutters, the neon and the magic. Claude Code and the Rive CLI wrote the scene in RML and the logic in Luau, and checked their own work with --verify and headless screenshots. Data binding drives the guest cards, the tracker and the mobile layout, and state machines run the card, the welcome and the finale. After rive push, I refined it by hand in the Rive Editor.

Features used: Rive CLI + GPU Canvas, plus Scripting, Data Binding and State Machines.

Loved this! I found 14 out of 15. Maybe the flying witch was the 15th and I missed clicking on it. Don't ever remove this! Bookmarked forever!
