TL;DR
OORT: Comet Vigil for P/2043 K1 Vesper is an AI-built web artwork centered on a fictional comet and observatory. Its star trails accumulate while a visitor stays, while scrolling moves the comet through a diagram and a timed shutter interaction records attention rather than a supposed discovery.
OORT: Comet Vigil for P/2043 K1 Vesper is an AI-built web artwork that makes a visitor’s time part of the piece: a seeded field of stars traces longer arcs as the page remains open, and the same local sky can resume when the visitor returns. The observatory and its comet are fictional; the documented development is an artistic and technical approach to showing waiting, not an astronomical observation or discovery.
The artwork is described as Room 170 of 175 in an exhibition series. It imagines an observatory watching P/2043 K1 Vesper over decades, then turns that premise into an interface. A canvas draws curved star trails around a point below the visible frame. Their length changes with elapsed time, using a logarithmic curve intended to make early changes apparent while leaving room for longer visits. A repeatable seed keeps the field consistent on a device, and local storage preserves elapsed time.
Other elements also respond to time or user input. Scrolling moves the comet through an inline SVG: its ion tail is shown pointing away from the sun, while its dust tail curves along an imagined orbit. The two paths share a progress value, linking the changing geometry to distance and year in the display. A range control changes a defocus view and its associated brightness estimate. A visitor can also hold a control briefly to open a simulated shutter; the site records a timestamp while leaving the comet unseen.
The design notes describe a dark, observatory-inspired palette: cyan marks the ion tail and readings, red-orange marks instructions and actions, and pale, dust-toned text carries longer passages. Display lettering is used for headings and measurements, while monospaced text presents coordinates and field notes. According to the description, the animation stops when the page is hidden, and visitors using reduced-motion settings receive a still version.
How OORT Makes Duration Visible
Most web pages treat time spent waiting as a gap between actions. OORT makes elapsed time part of its visual record: the trails accumulate, so remaining on the page changes what a visitor sees. Returning later is designed to continue that local exposure rather than reset the experience to an identical opening screen.
The shutter interaction follows the same idea. It logs a moment of attention but does not claim the visitor has seen or captured a real comet. That restraint matters because the project’s subject is the act of watching, not a fabricated scientific result. The combination of interface behavior and fictional astronomy gives the work a practical case study in how code can shape an artwork’s meaning.
For readers interested in AI-assisted creative work, the piece also makes its production brief and process part of the exhibition. The source describes a three-pass workflow—build, critique and visual refinement—along with a field guide explaining the exposure, orbit graphic, palette and typography. These are presented as the project’s process and design rationale, not as independent evidence that every requested quality target was tested or achieved.

The Fiction Behind the Observatory
OORT frames P/2043 K1 Vesper as a comet under long-term observation by an imagined community. The project description includes invented amateur logs, a decades-long vigil and a claimed historical provenance, including a “last seen 1608” detail. Those are elements of the artwork’s fiction; the source identifies the comet itself as fictional and does not present an astronomical record for it.
The published art direction called for a single-page site built with HTML, CSS and JavaScript, without frameworks, build tools, external requests or image assets. It also specified responsive layouts, keyboard focus styles, readable contrast, reduced-motion support and pausing animation when a browser tab is hidden. These details describe the brief; the material supplied does not include an independent technical audit, source-code review or measurements confirming performance across devices.
The exhibition description credits the original brief to Claude Fable 5, an art director, and says it was executed by a FABLE/175 pipeline. It points readers to a live room, a design guide and a broader hub of 175 rooms. The “held-light” technique refers to the artwork’s accumulating trails: the visitor’s continued presence becomes a trace rather than simply time spent consuming content.
“The page makes duration part of the artwork instead of treating it as time spent before the content.”

What the Project Does Not Verify
The source describes the artwork and its intended behavior but does not provide independent testing results, visitor data, or a technical audit. It is not clear how accurately the live site’s current behavior matches every requirement in the original brief, including performance at specified screen sizes and its accessibility targets.
P/2043 K1 Vesper is fictional, so its dates, orbit, brightness estimates and historical references should not be read as real astronomical information. The source also gives no publication date for the breakdown and no figures for audience reach or the project’s wider effect. The supplied material contains no statement from an astronomer or independent reviewer.

Visit the Room and Design Guide
The source directs readers to the live OORT room and its design guide, where the interface and its construction notes can be examined. Visitors can watch the background trails change, test the scroll-driven orbit graphic and try the simulated shutter interaction; the scene is an artistic representation, not a live comet feed.
The project also points to the hub containing all 175 exhibition rooms. No further release, update or external review is announced in the supplied material. Any assessment of how the site performs in practice will depend on inspecting the live room and its implementation.

Key Questions
Is P/2043 K1 Vesper a real comet?
No. The project identifies P/2043 K1 Vesper as fictional; its observatory and long-term vigil are part of the artwork.
What does “held light” mean in OORT?
It describes star trails that grow with elapsed time while the page is open. The site’s description says a repeatable seed and local storage let the same local sky resume on return.
What happens when a visitor uses the shutter?
Holding the control opens a simulated shutter and records a timestamp. The artwork does not show a comet sighting; it presents the interaction as a record of attention.
Does the site provide real astronomical measurements?
The project uses astronomy-inspired readings and graphics, but the comet is fictional. Its displayed orbit and brightness details should be understood as part of the artwork, not verified data about a real object.
Where can readers see the artwork?
The source links to the live OORT room and a design guide, and directs readers to the wider hub of 175 rooms. The supplied material does not give a publication date for the breakdown.
