Particle
The site for Particle, an inference platform for open-weight AI models. It's an unexpectedly joyful one: warm paper-cream panels ruled with thin lines and registration dots, a chunky serif wordmark, and a hero of animated op-art (a big hatched sun sliced by shifting horizontal bands of orange, pink, green, cyan and yellow) that recolours itself as you watch. Diagonal-striped colour blocks cap the footer, which closes on a giant line-shaded "Particle" wordmark. It's retro print graphics, 70s poster palette and tidy developer-docs restraint in one page.
