Halcyon — A Research Journal in Six Chapters
An astronaut drifting through dusk clouds opens a six-chapter research journal, with a chapter rail that fills as you read.
An independent research lab's journal told in six numbered chapters. The hero opens from a framed print to full bleed, a manifesto lights up word by word, and a salt-flat night plate pins and grows to fill the screen, followed by research cards, a stats and team strip and a newsletter sign-up, with a fixed chapter rail tracking where you are. It is one self-contained HTML file — inline CSS and JavaScript, no framework and no build step — with 2 AI-generated images. Under the hood: Vanilla JS, scroll-scrubbed chapter rail, clip-path image reveal pinned to scroll, word-by-word manifesto that lights up as you read, split-line Fraunces headline reveals. What a visitor can do: scroll to open the horizon plate from a framed print to full bleed, jump between chapters from the side rail, hover research cards to zoom the plate and turn the arrow ember, subscribe through the inline newsletter form. Best for: Independent research labs, Innovation journals & magazines, Think tanks & foundations, Science communicators. The exact image prompts are included, so the art can be regenerated or restyled with any image model.

Questions about Halcyon
Who is Halcyon for?
Halcyon is for designers, developers and agencies who want a site that moves like film and doesn't look like a template. Ask your AI to make it about your brand and it rewrites the copy, colours and images around the same build.
What is Halcyon built with?
Halcyon is built with HTML/CSS/JS. The source is a single HTML file: open it in a browser and it runs, with no build step. The prompt is written for coding agents such as Claude Code, Cursor and Antigravity.
Can I use Halcyon for a client project?
Yes. Every purchase includes a commercial licence: use it in your own projects and in work you deliver to clients, including paid client work, change and rebrand it, and publish the result with no credit needed. What you can't do is resell, share or republish the prompt or the source files themselves.
Should I buy the prompt or the source?
The prompt is the written brief that built the design: paste it into a coding agent such as Claude Code, Cursor or Antigravity and it builds the site on your computer, which you then refine. The source is the finished project itself, ready to run exactly as the preview shows. The source always includes the prompt.
Will the prompt give me exactly the preview?
Not exactly, and that's expected. A prompt is a starting point: AI output varies between tools and between runs, so plan to refine spacing, timing and copy. The source pack is the preview itself, finished and running.
Can I get a refund?
Single designs are final once delivered, unless something is wrong on our side: a broken or empty download, a pack that isn't what its page describes, or a double charge. Then email support@brandmotion.in with your receipt and we fix it or refund it. The full terms are on the refunds page.
