I built NIGHT.OS, an interactive haunted operating system that slowly becomes aware of the person using it.

What begins as a clean, futuristic desktop interface gradually turns into a possessed UI. A mysterious creature appears, watches and follows the cursor, manipulates interface elements, and eventually takes control of the system. The experience ends with a glitch-driven reveal before resetting back to the seemingly normal desktop.

I used Rive CLI to establish the interactive UI structure and RML workflow, then refined the visual direction, character, motion, interactions, and transitions in Rive. I also used GPU Canvas effects to create atmospheric distortion, CRT-style glitches, flickering light, fog, and visual reactions around the creature.

The goal was to make Halloween feel less like a collection of spooky graphics and more like an interactive story where the interface itself becomes the haunted character.
