Shiro keeps the front desk; every file has a keeper of its own. They all watch your cursor and like being poked. Poke one four times quickly and see what happens.

• Shiro

  Host of the crossing, narrator

  Host of the crossing. A small white dog from Kasukabe who took a job in Kolkata after one forgotten dinner too many. Poke him four times quickly and he gets dizzy.

1. Where the crossing comes from

   The home page's 3D street-signal hero is inspired by hirotos.com: one object, up close, with the camera orbiting it as you scroll. Ours is a Kolkata signal, modelled from scratch in Blender.

   Visit hirotos.com ↗

2. Black and white, on purpose

   Colour lives at the crossing, in the signal on the home page. Everything after it is paper and ink, so the work is the only thing asking for attention.

3. Type over images

   There are no photographs past the hero. Every figure is drawn in characters, live: small 3D scenes set in type, turning as you read, and diagrams that decode from noise as you reach them.

4. Thirty seconds, then the long read

   Every file opens with a TL;DR for people in a hurry. The full case study sits underneath for people who read.

5. A grid and three voices

   Twelve columns and a lot of air. Geist for names, Geist Mono for labels and figures, Newsreader for anything meant to be read.

6. Credits

   Shiro is a fan tribute to Crayon Shin-chan by Yoshito Usui; nothing from the series is reproduced, and his sprite is page-mascot’s dog, lightened. The other residents are from page-mascot by Kamran Ahmed (MIT), shown in greyscale. Built with Next.js, Hono, Three.js and a signal modelled in Blender, in Kolkata.
