About this app
Overview
Feryl is an experimental digital life simulation.
Feryl is a small digital creature that lives in a glass terrarium on your desktop.
It is not animated or scripted. Feryl runs on a simulated internal rhythm — a repeating breath cycle that drives everything it does: where it looks, when it moves, what it pays attention to, and how it reacts to the world around it.
Inside the enclosure are small objects, wandering insects, and a few simple ways to interact. You can watch Feryl explore, try to engage it in games, or speak to it through your microphone and see how it responds.
Feryl is less a traditional game and more a small living system you share space with.
Features
A Living Digital Creature
Feryl’s behavior emerges from an internal rhythm rather than scripted animations. Its movement, attention, and curiosity are driven by a continuous simulation.
A Terrarium World
Inside the enclosure you’ll find small objects and wandering beetles that share the space with Feryl. The insects follow the rock around the terrarium, and Feryl may ignore them, push past them, or occasionally become fascinated and follow them around.
Play Tic-Tac-Toe with Feryl
A tic-tac-toe board inside the terrarium allows you to try to play a game with Feryl.
Click the board to start a match. If Feryl becomes interested, it may approach the board and make its move. It might also wander away mid-game if something else captures its attention.
Over time, Feryl gradually improves through reinforcement learning after each match.
Voice Interaction
Feryl can hear you through your microphone and may respond with sounds of its own. Over time it adapts slightly to the vowel shapes and rhythms of the voices it hears.
Unique Creatures
Each Feryl is generated from a seed, producing a unique creature with its own timing, tendencies, and behavior patterns.
A Quiet, Ambient Experience
Feryl is designed to exist alongside your desktop rather than demand constant attention — something you can observe, interact with, and slowly get to know.
