Plenum

Plenum is a complete website for a technical or industry conference, a summit or any multi-track event. The demo is Baseload 27, two days for the engineers rebuilding the power grid, held in a 1957 shipyard hall. The look is a night shift: transformer black, fog and steel, with one sodium-lamp amber used only for what is live, current or yours, and square corners throughout.

The home page opens on a full-bleed night photograph that a pool of light follows across, with the event name set across the whole width. Further down, the live grid pins to the screen and scrolling plays the day: a now line moves across five rooms, sessions switch on as it reaches them and the clock in the corner keeps time. On phones it becomes a timeline that lights row by row. A second home page leads with the dates and five room lanes powering up.

There are 24 page types: programme with a saved "my day", a page per session, speakers and a page per speaker, four tracks and a page per track, a field day of site visits, passes with a side-by-side table and a demo checkout, a venue page with an interactive floor plan, partners, an archive of six editions, a journal, about, a call for speakers, questions, contact, terms, privacy, a style guide, a licence and changelog page and a 404. Five collections hold 24 sessions, 12 speakers, 6 editions, 8 articles and 12 partners. Every motion has a still version for people who turn motion off. The conference, people and prices are invented, and the images are for demonstration only, so replace them before you publish.
