Three.js MIT License v0.162 / v0.185

3D WebGL rendering library. It draws the CGV calorimeter visualisation (TileCal barrel, LAr barrel, HEC endcaps) and the coauthorship network on the About page.

Phosphor Icons MIT License v2.1.1

Icon family behind every glyph in the interface. Self-hosted as CSS masks over the current text colour, so only the icons this site uses are shipped.

GSAP GSAP Standard License v3.13.0

Animation engine behind the scroll choreography on the home page. Free for commercial use, plugins included, since Webflow released the whole library in April 2025.

Lenis MIT v1.3.26

Smooth scrolling, on every page. It runs off the same frame clock as the animations that read the scroll position, which is what the browser's own smoothing could not do. By darkroom.engineering.

Purple light waves, by Nicola Narracci Pexels License

The panel that runs off the right-hand edge of About & Science on the home page, passing behind the publications card. Interpolated to sixty frames a second and masked so it thins out towards the edge of the window; otherwise as it was shot.

Aurora borealis, by Mohammed Abubakr Pexels License

The northern lights over a pine wood, on the AURORA project card. Cropped, graded and cut into a loop that runs forward then backward, so it turns over without a seam.

Robotic hand, by Yaroslav Shuraev Pexels License

A robotic hand opening in front of a vintage television, on the Aurora Intelligence card. Cropped from vertical, graded, and cut into a loop that runs forward then backward, so it turns over without a seam.

Circuit board, by Soumya Pexels License

The board on the SAPHO project card. Filmed in monochrome and graded here to the project's own gold, on the black the card shares with it.

CERN photographs CERN Terms of Use

The aerial view of the Meyrin site, the Globe, the LHC tunnel and its dipole magnet, the ATLAS cutaway and layer diagram, the TileCal module, the LAr accordion, the control room, the trigger chain and the FCC concept.

ATLAS control-room building, by TomIsNotResponding CC0 1.0

The second stop of the descent on the CERN page. The mural on the building is ATLAS, painted in 2010 by Josef Kristofoletti at half the scale of the detector below it. Photograph from Wikimedia Commons, dedicated to the public domain.

Map data, OpenStreetMap ODbL

The ground drawn over the LHC in the CERN page hero: the France–Switzerland border and the watercourses of the Meyrin countryside, fetched once by tools/build-meyrin-map.js and committed as data. © OpenStreetMap contributors, under the Open Database License.

Sections through the four experiments Drawn from published geometry

The four pins in the CERN page hero are sections through the machines themselves: transverse cuts of ATLAS, CMS and ALICE at their published radii, and LHCb from the side, since it is a forward spectrometer and not a barrel. Drawn by tools/build-experiment-figures.js from the collaborations' published geometry. The drawings are ours, the numbers are theirs.

Standard Model of Elementary Particles, by Cush Public domain

The particle table used on the CERN page. Drawn for Wikimedia Commons and released to the public domain by its author.

HYG Stellar Database CC BY-SA 4.0 5,044 stars

Hipparcos, Yale and Gliese combined. The sky over the home page is this catalogue drawn as it is: every star down to magnitude 6 at its own position, with its own brightness and its own colour. Taken in the packed form d3-celestial distributes.

TileCal reference pulse shape ATLAS Collaboration

The figure on the CERN page. The shaped pulse, its 150 ns width, the seven samples 25 ns apart and the out-of-time signal from the following bunch crossing all come from J. M. de Seixas, on behalf of the ATLAS Collaboration, "The TileCal Energy Reconstruction for LHC Run2 and Future Perspectives". The curve is redrawn from the published landmarks and tabulated by tools/build-tilecal-pulse.js; the sample values follow from it and are not measured ADC counts.

Geist SIL OFL 1.1

Primary sans-serif, carrying body text and interface. A contemporary grotesque, kept quiet so it does not compete with the display face. By Vercel.

Bodoni Moda SIL OFL 1.1

Display serif behind every heading. A didone, with the extreme stroke contrast the style is known for, and an optical size axis that keeps the hairlines fine at large sizes and solid at small ones. By Indestructible Type.

IBM Plex Mono SIL OFL 1.1

Monospace typeface used for version tags, code, figures and technical labels.
