I have registered an additional business name: Frameshift Design.
I'm working on my next step in my business: radical communication solutions. I will be helping science and social organizations tell their most important stories in a radically different way, so they can make the impact they deserve.

I just stumbled upon featherbase, a database of feather pictures from a bunch of bird species.🪶

So pretty!

There are countless websites that generate color palettes, but I needed a reusable package for my own apps. So I built dittoTones. 🟣

It mimics the perceptual DNA (Lightness/Chroma curves) of popular systems and blends them with your target hue → meodai.github.io/dittoTones/

I must say, vive coding can produce workable code, but it also turns quite a bit into a patchwork of working parts, because AI misses the overall intention/structure....

INGRAPHICS is a „magazine for visual thinkers“ — and I was kindly invited to contribute a double spread. I created a visual overview of the long history of Elon Musk‘s not-quite-materialized predictions on autonomous cars 🤖🚙 (en.wikipedia.org/wiki/List_of...)

SveltePlot 0.7 is out! Lots of new features since the last time I posted here: 🎉 jitter transform, 🐝 dodge transform (for beeswarm plots), 🎉 stackMarimekko, 📸 image mark, and most recently the 🧇 waffle mark! And the website now features a ton of examples.

We just shipped a desktop version of Rowboat that runs fully offline: rowboat.net

It's silly fast, the app loads almost instantly, and you can plunk a multiple gigabyte dataset into it and it just starts spilling out answers.

Lots more in the pipeline; try it out and send us your feedback!
We just launched a desktop version of Rowboat!

* Open much larger files (offline!)
* Own Desktop as a one-time purchase.
* Use a double-clickable app that’s even faster than the web version.

Browser or desktop, your data never leaves your machine.
