I spent eight years building tools that asked designers to translate decisions into code, or asked engineers to translate code into design. Neither side ever loved it. LSD is what happened when I stopped trying to bridge the two and started designing a substrate underneath them.

The version of the framework you can download today is the third one I've built. The first two taught me that "design system" wasn't actually a thing — it was three things in a trenchcoat. Once I separated tokens, behaviours and surfaces into their own pillars, everything got easier. This version is the answer.

I'm available for press conversations, podcasts and conference talks. The work matters more to me than the credit, so feel free to write about LSD without quoting me — or to put me on the line for an hour and grill me. Both are fine.
