01 / A connected platform
One system.
Several ways to understand it.
The calendar is one entrance, not the extent of the work. The platform moves between time, place, explanation, and reuse.
Surface & place
Optical cartography, named features and coordinate-based inspection.
Inspect the atlasResearch & method
Research literature, computational documentation and the limits of each model.
Explore the researchData & reuse
Calculation modules, public API documentation, embeds and machine-facing tools.
Follow a calculationThe design challenge
Depth without
an entrance exam.
A phase, a place on the Moon, and an orbital cycle describe different things. The interface needs to connect them without making them interchangeable.
I designed multiple levels of entry: a readable first observation, an instrument to test it, and a method to inspect when you want to go further.
02 / Time becomes tangible
Change the date.
Watch the system respond.
The Moon, calendar, numerical reading, and clock share one selected date. An interaction exposes the relationship more clearly than a still image can.
The orbital clock
One Moon.
Five different cycles.
A month depends on what you measure against: the Sun, the stars, the orbital nodes, or the Moon’s closest approach. Select a cycle to follow its rhythm.

01 One date drives several representations. The calendar’s phase symbols lead into a more detailed reading.
02 The renderer uses the product’s calculation modules, with a fixed noon-UTC sample and a clearly named observer.

A world to inspect.
Not just an image to admire.
Select a named feature, center it, and add the coordinate grid. A surface becomes useful when you can connect what you see to where it is.

The calculation is not trapped inside the picture. Select a value to see how the platform turns a method into an interface—and data another tool can use.

A system decision
Shared calculation.
Purposeful views.
The clock compares mean cycles; the selected-day view calculates an ephemeris. Naming that distinction avoids making a beautiful diagram look more precise than its model.
An editorial decision
Observation is not
interpretation.
Calculated readings, research material, and reflective almanac notes have different evidential roles. The product gives them separate labels and places, rather than blending them into a single claim.
Read the methodology05 / Project record
Keep the work.
Keep its context.
The interactive exhibits are bounded, locally hosted source excerpts. The earlier captures remain available as a historical record—not the main way to experience the work.
Historical interface captures Five views / 25 Sept 2026
Implementation, provenance & scope
These exhibits use versioned copies of Lunologium’s clock model, ephemeris module, projection geometry, and WebGL renderer. Controls and composition are adapted for this case study. They do not depend on the live site staying online.
The 2026 date range samples each day at 12:00 UTC. The ephemeris fixes the observer at Greenwich (51.4769° N, 0.0005° W, elevation 46 m). Distance is observer-relative; the Moon illustration is lunar-north-up, not a view from that local horizon. Mean clock cycles are not eclipse predictions.
The atlas exposes six product catalogue entries and the optical mosaic. It does not present conceptual temperature or gravity illustrations as measured rasters. Role credit follows the existing portfolio record; no independent user, accuracy, or business-outcome claims are added.
