Body
The fly’s body is the NeuroMechFly model: 69 segments derived from micro-CT scans of a female Drosophila melanogaster, articulated joint by joint.

Our fly, named Specimen 237: a micro-CT-derived body with 69 articulated segments, and the MaleCNS v1.0 nervous system. Drag to rotate both.
The fly’s body is the NeuroMechFly model: 69 segments derived from micro-CT scans of a female Drosophila melanogaster, articulated joint by joint.
The nervous system is MaleCNS v1.0 from FlyEM at HHMI Janelia: the complete male central nervous system, run as 166,700 leaky integrate-and-fire units with fixed weights.
Each experiment renders what the fly sees from its own head. Display settings change what you see, never what it sees.
Beyond the eyes. Dedicated experiments deliver smell, taste, touch, hearing, temperature, humidity and limb-position input to the fly’s matching sensory neurons.
The body and the nervous system come from different specimens and are not anatomically registered. Read the specimen file
Each scene is built and rendered in 3D. What the fly sees is rendered from its own head and delivered, as retinal input, to a spiking model of the complete male fruit fly central nervous system. The spikes that follow are recorded, not drawn.
Experiment No. 0020 · Master Mason
A 52-stage lodge ceremony condensed from Duncan’s Ritual of Freemasonry (1866). Twenty-seven flies hold the offices and walk the circuits. Our fly is the candidate.

No. 0020
The fly is the candidate in a Third Degree ceremony of 52 stages following Duncan's 1866 monitor, representing Hiram Abiff in the legend of Hiram Abiff, through the raising and the closing.

No. 0040
The fly, as aspirant, undertakes a condensed six-month Abramelin operation in a domestic oratory, from preparation and increasing prayer to the guardian and exterior convocations.

No. 0042
The fly occupies the candidate's role in a complete presentation of a supplied Thirty-first Degree ritual text, from the cave prelude through four Egyptian altars, the weighing, judgment and investiture to the return to the cave.

No. 0036
The fly, enlarged to tens of metres, walks a looping five-stop survey route across Martian terrain built from published HiRISE stereo elevation models and aligned orthoimages.

No. 0032
The fly attends a condensed Sunday Mass in Ordinary Time as one of 24 fly parishioners, following U.S. postures and receiving Communion individually from the priest.

No. 0033
The fly watches a red laser projection on a wall as the room melts into a jeweled tunnel, twelve holographic fly figures present geometric jewels, and the room reassembles to its opening state.
