Good humans, I wrote a book. Took me 10 yrs. Share it with anyone who wants to understand the minds they're designing for and the mind they're designing with. 40 chapters free to read. 📘 productdesignpsychology.com ❤️

Comments right on your running prototype. Want to try it out on a project you’re working on? Send me a dm.

Anyone here building a prototype and looking for feedback from others. I’m building Tonen. Think Figma-style comments and follow mode, but directly on running prototypes instead of design files. The beta and I are ready for people to try it out. Shoot me a dm.

Had a lot of fun designing this funky wordmark for Tonen.

Animated ASCII artwork is done and implemented the actual Tonen tool itself on the Tonen landing page.

This animated ASCII artwork was so much fun to create.

So cool to now see Claude reading my comments in Tonen and starts fixing things while I leave feedback throughout the project. And not unimportant; the builders of the project now wear hard hats!

The name of this app is Tonen (Dutch for ‘to show’), after connecting to its mcp you can just ask Claude to add the Tonen comment layer and get a share link. People can comment on your running build like they would on a design file. Comments are pinned to html elements.

As design moves from static files straight into code, I miss one thing: comments/feedback right on the designs. I thought I’d build this tool for myself to allow co-workers and clients to comment directly on a running prototype, just like in a design file.

Bennie Bus made it to Norway, although very very slowly.

Yesssss! After 9 months we finally picked up Bennie, our restored 1970 VW T2a. Just in time for our road trip to Norway.

Bennie Bus is almost here. The photo on the right was 9 months ago. The one on the left is today. Turns out restoring a VW bus takes about as long as having a baby.

Not sure if I can blame AI, but somehow every landing page feels boringly the same nowadays. Not bad, just the same.

One for the road. One for the dirt. Both equally good for the soul.

Building the website for my book and creating the illustrations has probably been the most enjoyable part of the project. The site is built with the Hugo static site generator, partly hand-coded and partly with Codex. The illustrations were drawn in Procreate on my iPad.

They made some good progress on our bus. Our daughters named him Bennie. Hopefully he’ll be ready in time for summer vacation. 🤞
