Field notes from the internetSeptember 2026 · The fly edition

A very
busy fly.

You saw the lightsabers, bitcoin, and FlyTok.
There is also a skateboard. And a robot. And HR.

The posts behind the flies.

Direct X posts for 14 of the 16 examples. These are creator posts, not a ranking by virality; the DOOM link is the later widely shared clip. I could not locate the exact Flybook post or an associated Workday post. Skip to the preview gallery ↓

Skateboarding to dubstep

Alexey Fateev · @superalesha

A tiny skateboard session ends when the bass drops and the fly falls off. Tony Hawk: Pro Drosophila.

What this actually shows

A separate clip from the earlier electronic-music demo; the description follows the creator's presentation, not an independent biological validation.

Doing the YMCA

Dhruv Bhatia · @dhruvbhatia0

Four tones cue four letter-shaped poses. The creator jokes that the fly has traded its capacity for love for the YMCA.

What this actually shows

The claim about losing love is a joke, not an established neuroscience finding.

Getting a body. Trying to leave.

Alexey Fateev · @superalesha

A fly-model-controlled Stack-chan robot jerks its head away from an approaching hand. Its first interaction with the physical world is an attempted exit.

What this actually shows

The creator describes mapping a simulated escape circuit to the robot's head movement. This is not a conscious fly uploaded into a robot.

The Flybook

Alex Wormuth · @nftechie_

Facebook for six flies: profiles, a wall, and the question of who gets a buzz back. Three male and three female models mingle in a digital fruit bowl.

What this actually shows

The project explicitly says learned social preference is an open question. Its illustrated profiles are not literal fly-authored text.

FlappyFly

Alexey Fateev · @superalesha

A fly plays Flappy Bird and is, by its creator's own account, terrible at it. Somehow the one game a fly should be qualified for.

What this actually shows

An engineered mapping stimulates a simulated escape circuit as pipes approach; this is not evidence of a fly understanding the game.

A rave it did not request

Alexey Fateev · @superalesha

Heavy electronic music sends the virtual fly staggering and eventually to the floor. The prequel to the skateboard incident.

What this actually shows

This is the creator's music-to-simulation demo; the clip does not establish suffering or musical experience.

Super Mario 64

Jessica Paquette · @barrelshifter

A fly-model-driven Mario attempts the Mushroom Kingdom. The species crossover nobody needed, but everyone needed to see.

What this actually shows

A playful game-control demonstration, not a validated claim of competent or independently learned play.

Bad Apple!! on its brain

Linguine Labs · @linguinelabs

The internet's inevitable Bad Apple port, except the screen is a visualization of a fly's neurons.

What this actually shows

The neural visualization is being used as a display. Do not confuse that with a fly understanding or performing the music.

Preview from DOOM
09 Games

DOOM

Alex Wormuth · @nftechie_

Of course someone asked whether the fly could run DOOM. Game frames feed simulated sensory neurons; their activity is mapped to the controls.

What this actually shows

The original post asks whether it will learn to survive. It does not establish that it has learned to play well.

A Minecraft life

Evan Sinclair Smith · @evnsnclr

A connectome-driven fly moves into Minecraft. An entire sandbox universe, now available to an insect.

What this actually shows

The creator explicitly describes this as an interactive connectome experiment, not a complete recreation of a living fly or evidence of consciousness.

11 Games

Fly Escape Room

David Zhang · @dzhng

Arrange objects in a house and try to get the fly NPCs outside. Finally, a video game about the real-life difficulty of showing a fly an open window.

What this actually shows

The current repository says each fly uses a selected connectome subgraph with approximate dynamics, sensory inputs, and movement rules.

Fruit fly heaven

Macroblock · @sainimatic

After the games and involuntary music sessions, someone proposes an endless world of fruit, trees, and peaceful flying.

What this actually shows

The original is an in-development proposal with a screenshot, not a verified released game.

PTO: pendinga fly that works here.
13 Bonus · adjacent project

A job. With HR.

Kainos Workday AI CoE

An agent turns the fly model's signals into meal-voucher and PTO requests. Startle it and it may file a workplace safety complaint about you.

What this actually shows

A separate FlyWire-based demo, not necessarily part of this week's MaleCNS wave. A software agent interprets signals and files requests; the fly itself is not operating HR software.

FlyTok

Matty Hempstead · @mattyhempstead

A fly doomscrolls its own short-video feed, with artificial dopamine stimulation. The creator's stated ambition: out-happy all other flies combined.

What this actually shows

The happiness claim is the creator's humorous framing. Simulated dopamine activity does not establish subjective enjoyment.

Bitcoin trader / StonkFly

Alex Wormuth · @nftechie_

The creator gives the fly model $100 and maps neural activity to cryptocurrency trading decisions. A hedge fund with an extremely small research department.

What this actually shows

The project describes approximate neurons and an engineered trading interface. Execution status can change; this roundup does not verify profits or continuous live trading.

Beat Saber

Lyra Bubbles · @_lyraaaa_

The lightsaber clip: a virtual fly swings through Beat Saber. Fruit flies now have a more interesting weekend than most of us.

What this actually shows

The creator clarified that the motor output reproduces a recorded sequence. The viral clip does not yet demonstrate independent Beat Saber play.
