An experimental web-based drawing tool where you configure the pen by connecting nodes in a graphical programming interface.

This started as an attempt to reverse-engineer the branding for RCA Show 2019 by Regular Practice. The idea for the node-based editor comes primarily from Blender’s shader editor (because I use it a lot), though the idea of Flow-Based Programming is much older than that. I’m using IBM Plex Sans, which works beautifully as an interface typeface.

It’s also part of a continued exploration of visual expressions of mathematics – see Gradient Drawings from earlier this year. I like the idea that even though I only wrote a handful of different nodes (a couple of colour pickers and some basic math functions), the space of possible pens is enormous.

This is also my first React app. I made a conscious decision to write this in React because building a real-world thing tends to be the best way to learn new technology for me. It probably slowed me down (especially at the start, when I was still coming to grips with JSX and the top-down dataflow), but it’s worth the effort.

I didn’t read much outside the official React documentation, which has to be one of the best pieces of technical writing out there. I’m convinced the quality of the onboarding process is a major reason why React is as succesful as it is.
