These projects are all in various stages of abandonment, but once upon a time I thought each of them was a good idea.

Maths
A demo for the Frinj ClojureScript library, an evaluator for URMs, an evaluator for Legendre symbols, and a graph database.
Sport
A different way of visualising football league tables, and a tool for charting historical league positions.
Music
A database of Late Junction playlists, a mapper for Last.fm play history, and an aggregator for gigs on Myspace (yes, really!).
Language
A flashcard tool with Spanish verbs, and a timeline chart for Goodreads history.
Games
A port of a game from The Fool and His Money, and an unimpressive Ludum Dare effort.

Elsewhere, I'm on GitLab, GitHub, Goodreads, Flickr, and Last.fm.
