A collection of small web-based utilities and tools I've created, mostly with the help of Claude. Please also see my main site and blog.
An implementation of the Werner cellular automaton model for sand dune formation, with adjustable parameters and nice hillshade views.
An implementation of the 'Missing Vowels' round from the Only Connect TV quiz show. Enter some words/phrases, and this will take out the vowels and squish up the consonants - your task is to guess the word/phrase.
A utility that breaks down URLs into their component parts, making it easy to inspect query parameters - I built this as I end up fiddling with query parameters a lot at work.
