Claude was able to produce a custom app to show the relation between DNA sequence and protein sequence.

InfoCards

InfoCards - Rich Tooltips

February 18, 2026 📣 Announcement

These tooltips have 'Optical Stability' and they stay out of the way. They provide a reusable master-detail paradigm that works well for dense data.

OmniChart

OmniChart - A Morphing Chart Set

January 19, 2026 📣 Announcement

I needed 'the standard' chart types, pie chart, line chart, bar chart, spider plot, and decided to do them all in one. They morph into each other.

ASCII Tree

ASCII Tree - A documentation tool

January 1, 2026 📣 Announcement

Using the box drawing │,├, ─,└ symbols to make an ASCII-Art tree is fiddly and takes time. Claude one-shotted a small online tool to do it, from a single prompt.

Small Sounds

Small Sounds - A Sound Effects DSL

December 8, 2025 📣 Announcement

I didn't want to upload lots of different mp3 files. Instead I wanted to generate short simple sound effects, client side. This is the result.

LCARS

The LCARS user interface from Star Trek TNG actually has some desirable properties as a user interface.

AIs struggle with understanding shapes. Here I got Claude to make tags with the end shapes I wanted.

Mining Base on Mars

Work in Progress - Martian Base

September 12, 2025 ⚡️ Spike Solution

Cards are crucial to a software project I am working on. Here a spike solution begins to rework the card ideas, via a clicker-style Mars-base game. This code, co-produced with AI, helps to build a card based dashboard.

This spike solution also explores visual metaphors to track resource exchanges.
