Our Lab for AI Experiments, Data Stories and Interactive Tools

Explore our growing collection of AI-powered experiments, interactive analyses, data stories and wonderfully unnecessary tools. Each one is built with the same engineering we use for client projects.

PHP2Shell

Both bugs are a few lines in PHP's engine. One left half-built values on the stack when memory ran out; the other skipped clearing a stale pointer on the fast-shutdown path that production servers use. Chained, they give remote code execution.

Why we build these

Serious engineering, playful questions

Real, open data

Every experiment names its sources and licences. No invented numbers, no black boxes.

AI-assisted, human-checked

We use AI to move from question to working app fast, and check every step like client work.

Same stack as your project

Data pipelines, analytics and AI: the skills behind these experiments are the ones we bring to data platforms.
