The film opens not with a title card, but with a soundscape: the oppressive hum of cicadas mixed with low-frequency radiation static. The visual is a verisimilitude of a desert at high noon, rendered in a deliberately degraded 3D aesthetic—reminiscent of early PlayStation 2 tech demos, but filtered through a modern glitch-art lens.
The "Beasts" of the title are not animals in the traditional sense. They are colossal, skeletal constructs—think cetacean vertebrae mixed with industrial rebar. These creatures lie half-buried in dunes of salt-white ash. They do not move. They do not breathe. They simmer.
According to the sparse description left by Animo Pron (since deleted from their primary account but archived by fans), the "Skeleton Test" refers to a proprietary rigging system designed to simulate thermal distortion around osseous matter. In layman's terms: Animo Pron built a digital skeleton and asked, "What happens to the light when it touches the dead?"
The subtitle "-Skeleton Test-" is crucial. Unlike a finished narrative, this piece is an exercise. The camera moves with the clinical detachment of a radiologist panning over an X-ray. We see: Beasts In The Sun -Skeleton Test- By Animo Pron -2021-

Lyrically and sonically, "Skeleton Test" explores vulnerability, decay, and the clinical gaze. If Beasts in the Sun evokes sun-baked mythology, this song flips that warmth into scrutiny—the sun as an examiner, bleaching flesh to reveal structure. The emotional center is ambiguity: a tension between tenderness (a delicate synth motif that recurs) and inspection (the song’s procedural staccato).
The mood is nocturnal despite the title: a twilight laboratory where relics of self are measured, cataloged, and left to stand. The film opens not with a title card,
Since its release, Beasts In The Sun -Skeleton Test- has influenced a micro-genre of "osteological animation." Several indie game developers have cited the test as inspiration for enemy designs in survival games, particularly in the 2022 release Salt & Bone and the 2023 walking simulator Parched.
Art students on platforms like Cara and Pillowfort have created "Pron Studies," attempting to replicate the cascading joint lag technique. Animo Pron themselves has remained silent since mid-2022, leading to speculation that Beasts In The Sun was their final statement—a perfect, desolate loop of beasts running forever under an indifferent sun.
The title is deliberately modular. Let’s break it down: The animation itself is short but searing
Beasts In The Sun -Skeleton Test- is a short experimental animation study by digital artist Animo Pron. The piece depicts a surreal, sun-scorched landscape where skeletal animal forms—part mechanical, part organic—slowly emerge from cracked earth. The “test” in the title refers to the artist’s exploration of skeletal rigging, environmental lighting, and atmospheric distortion. Rather than a narrative, the work functions as a technical and poetic vignette: a moment where heat, decay, and memory fuse into motion.
The animation itself is short but searing. It opens on a 4:3 aspect ratio frame, tinted with a solarized filter—whites are blown out, shadows are deep purple. The setting is a cracked salt flat under a monolithic sun.
