PostHog
A playful skeuomorphic desktop-OS interface where the marketing site is dressed as a tan-canvas operating system — file icons line the edges, the main content sits inside a draggable "home.mdx" application window with title bar and toolbar chrome, and hand-drawn hedgehog illustrations supply brand warmth. Voltage comes from a single hot-orange CTA (#f54e00) against a warm beige (#e1d7c2) desktop, the rounded Open Runde display face, and the deliberately retro window-frame metaphor rather than from gradients or photography.
